The price trend of Pentane, Hexane and Heptane after the holiday

by David Zhang, Sales Manager at Junyuan Petroleum Group

In 2022, the price changes of pentane, hexane and heptane during the new year’s Day holiday and the prospect of the trend after the holiday. On the eve of the New Year’s Day holiday, domestic pentane and hexane pushed up all the way, with an increase of nearly 100 yuan per ton. According to the real-time exchange rate of RMB against the US dollar today, it is about US $16 / ton. The price of n-Heptane products fell, with a decrease of up to 500 yuan per ton, about US $78/MT. Supply tightening is the main boost. On the one hand, Junyuan Petroleum Group, a leading manufacturer of Pentane, Hexane and Heptane, took the lead in increasing the quotation while controlling the volume of shipments; On the other hand, the replenishment of domestic trade ships is limited, and the impact on the delayed arrival of imported ships is small. The inventory in Qingdao and Shanghai ports continues to be less than 30,000 tons. The cargo holders have no shipping pressure, have a positive attitude, push up actively, and focus all the way up.
During the New Year’s Day holiday, the market atmosphere was relatively quiet, and most operators withdrew from the market to wait and see, waiting for the market to become clear after the festival.
Changes in main factors affecting price fluctuations
Cost Side
Firstly, based on the analysis of the price trend of main raw materials for pentane, hexane and heptane production, the price of naphtha rose before the new year’s Day holiday. Considering the decrease of imported cargoes from January to February, the new n-Heptane unit is put into operation, and coincides with the extension of the unloading period of n-Heptane import ships on the shore, n-Heptane is expected to be transferred to the warehouse removal stage; However, it should also be noted that after the new n-Heptane production unit is put into operation, the negative pressure of non integrated n-Heptane caused by intensified industry competition will directly pull down the price of n-Heptane. Therefore, it is expected that in the first ten days of January, n-Heptane will mainly fluctuate at a low level, focusing on the shipping situation in Shanghai and Qingdao and the production process of downstream n-Heptane.
Secondly, considering the average contract price, the starting point of the average price of Pentane and Hexane in January is high, and there is little room for contract households to make profit and ship goods, so it needs to be treated with caution.
Supply Side
From the perspective of domestic supply, it is reported that the major pentane, hexane and heptane manufacturers planned to store, shut down and overhaul their units in January, and the contract has corresponding reduction expectations. In addition, considering the immediate demand or stock mood in the first ten days, it is expected that there will be little pressure on domestic goods supply in the first ten days.

Prices of Hydrocarbons have been stable in the last three days

by David Zhang, Sales Manager at Junyuan Petroleum Group

Analysis on price fluctuation of pentane products in 2021

Hydrocarbon prices have been stable in the last three days. Today is the last day of China's New Year's Day holiday. Each chemical enterprise has not started yet, and the order delivery of each solvent factory is carried out as usual. The staff of the sales department, freight forwarding enterprise, logistics enterprise and the production and loading and unloading team of the factory are usually on duty on a 7 / 24 rotation all year round.

Analysis on price fluctuation of pentane products in 2021

In 2021, the price of domestic pentane products rose across the board compared with last year. The price trend of the whole year is obvious from the figure, which is higher than that of the previous two years. Especially at the end of October, the price soared to a historic high, and the annual low was at the beginning of the year. Throughout the year, the supply and demand factors of n-Pentane, Isopentane, Foaming Agent and Cyclopentane changed a lot. In February and March, the extremely cold weather in Europe and America disturbed the supply pattern and flow direction, and the production units at home and abroad were unstable. In the second half of the year, the domestic units stopped periodically, the supply decreased, and the market price gradually showed an upward trend. With the off-season of downstream demand, the export cost increased, the market focus returned, and the phased decline at the end of the year ended.
Throughout the year, in addition to the fundamentals of supply and demand, the market is still affected by many factors: the domestic epidemic situation is effectively controlled, but the foreign epidemic situation is continuous, which has a certain inhibition on exports and shipping, and the crude oil market is volatile. In the second half of the year, the global market boom is gradually depressed, and it is difficult for the solvent industry terminal to improve. The demand side is gradually unable to bear high-priced raw materials, so it is "GivingUp" waiting at the end of the year, Hydrocarbon production plants are passive under pressure.
In the twinkling of an eye, the Spring Festival in 2022 is coming. China's Spring Festival is as important as Christmas in the West. It is believed that many people are looking forward to returning home to reunite with their relatives, the annual Spring Festival transportation is about to start, and college students are about to have a winter vacation. The Spring Festival is a festival that every Chinese people look forward to.

Product Knowledge Sharing Today:

Chemical industry chain: raw materials → intermediates → consumer goods
Analyze the situation from the chemical industry chain. The direction of basic chemical industry university can be analyzed from syllogism: upstream raw materials, intermediate products and downstream conditions. Upstream raw materials are simply summarized as crude oil, coal mines and various chemical minerals (lithium, potassium and phosphate). Downstream can be summarized in four words: food, clothing, housing and transportation. All chemical sub industries can implement these four words. Clothing: textile industry, chemical products related to the textile industry, as well as fibers and polyester used in the textile industry. Food: chemical food processing industry, agrochemical sector, nitrogen, phosphorus and potassium, compound fertilizer, pesticides, food additives and medicine. Housing: real estate, real estate related, such as household appliances. OK: automobile, high-speed railway, rubber sub industry in tires, etc.

What are Hydrocarbons?
Core tip: Hydrocarbon products are widely used in daily production and life. Hydrocarbons are divided into alkanes, cycloalkanes and aromatic hydrocarbons. HCR433B hydrocarbon refrigerant is the most representative in commercial life, while HCR436A hydrocarbon refrigerant is the most representative in automobile.
“Hydrocarbon” is a common name for hydrocarbons. Organic compounds composed only of carbon and hydrogen are called hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine vapor and oxygen to produce hydrocarbon derivatives. Saturated hydrocarbons (and benzene) do not react with strong acids, bases and strong oxidants (such as potassium permanganate), but unsaturated hydrocarbons (olefins, alkynes and benzene homologues) can be oxidized or react with hydrogen halide. There are many kinds of hydrocarbons, and there are more than 2000 kinds of hydrocarbons with known structures. Hydrocarbon is the parent of organic compounds. Other kinds of organic compounds can be regarded as derivatives generated by the substitution of one or more hydrogen atoms in hydrocarbon molecules by atoms or atomic groups of other elements.
Hydrocarbons in petroleum
Hydrocarbon in Chinese is the abbreviation of hydrocarbon, which is composed of “fire” in “carbon” and “巠” in “hydrogen”. Hydrocarbons are divided into saturated hydrocarbons and unsaturated hydrocarbons. Most hydrocarbons in petroleum are saturated hydrocarbons, while unsaturated hydrocarbons such as ethylene and acetylene can be obtained only in the process of petroleum processing. There are three types of hydrocarbons in petroleum:
(1) Alkane
It is a chain hydrocarbon with single bond between carbon atoms. Due to the different number of carbon and hydrogen atoms that make up hydrocarbons, petroleum contains hydrocarbon molecules with great and small differences. Alkanes are named according to the carbon atoms and number contained in the molecule. Those with less than 10 carbon atoms are represented by a, B, C, D, e, hexane, heptane, octane, nonane and decane from 1 to 10. Those with more than 11 carbon atoms are represented by numbers. Alkanes in petroleum include normal alkanes and isoalkanes. The content of n-alkanes in paraffin based petroleum is high; The content of isoalkanes in pitch based petroleum is high. Alkanes are also called alkane hydrocarbons. The general formula of the molecular formula of alkanes is CnH2n + 2, where n represents the number of carbon atoms in the molecule. 2n + 2 represents the number of hydrogen atoms. Under normal temperature and pressure, C1-C4 alkanes are gaseous and exist in natural gas; C5-c16 alkanes are liquid and the main component of petroleum; Alkanes above C16 are solid.
(2) Cycloalkanes
As the name suggests, it is a ring structure. The most common is a ring composed of five or six carbon atoms. The former is called cyclopentane and the latter is called cyclohexane. The general formula of the molecular formula of cycloalkanes is CnH2n. Cycloalkanes are also called cycloalkanes.
(3) Aromatic hydrocarbon
Also known as aromatic hydrocarbons. It is generally composed of one or more six membered rings with special structure. The simplest aromatic hydrocarbons are benzene, toluene and xylene. They can be obtained from the production of platinum reforming unit in the oil refining process. The general formula of the molecular formula of aromatic hydrocarbons is CNH2N-6.
To sum up, hydrocarbons exist in many things, such as fuels and cleaning agents, and are widely used in daily life.

The organic solvent purification system can process solvents:
Aromatic and aliphatic hydrocarbons: Pentane, n-Hexane, Cyclohexane, n-Heptane, Toluene, Benzene
Ethers: ether, tetrahydrofuran, dimethyl ether
Chlorinated solvent: dichloromethane, chloroform, chlorobenzene
Amine solvents: triethylamine, pyridine, diisopropyl ethyl amine
Alcohol: methanol, ethanol
Other general solvents: acetonitrile, dimethylformamide, dimethyl sulfoxide, acetone

The prices of pentane, hexane and blowing agent rose collectively

by David Zhang, Sales Manager at Junyuan Petroleum Group

2021/12/31. USD TO CNY TODAY.

Actual USD to CNY exchange rate equal to 6.3545 Chinese Yuans per 1 Dollar. Today’s range: 6.3364-6.3781. Previous day close: 6.3730. Change for today -0.0185, -0.29%. Inverse rate: CNY to USD.
DOWN 6.3545 -0.29%
Opening price of crude oil (WTI) today: 76.668/barrel (↑ 0.08, up 0.1%)
Today’s opening price of crude oil (Brent): 78.818/barrel (, 0.25, a decrease rate of 0.32%)
Opening price of Shanghai crude oil futures: 496 yuan / barrel (↑ 5.7)
International crude oil cost today: 4561 yuan / ton (estimated by formula)
n-Pentane, 95%, increased by 1.59%, and high purity pentane, 99%, increased by 1.32%.
Isoopentane, 95%, increased by 1.29 percentage points, and isoopentane, 99%, increased by 1.14 percentage points.
Among pentane blowing agents/mixed pentanes, the price of which Isopentane accounted for a large proportion, increased by 1.67 percentage points, and that of n-Pentane increased by 1.59 percentage points. After the price of pentane foaming agent decreased by 0.84% on December 28, the price rose yesterday and today.
Cyclopentane product prices remained unchanged today.
Today’s prices of n-Hexane products have not changed except for 90% and 99% products of high purity. The prices of the other three products have increased. The prices of n-Hexane, 60%, n-Hexane, 70% and n-Hexane,80% have increased by 1.33%, 1.30% respectively.
The price of high-purity Heptane products has not changed since it decreased by 6.58% on December 28, and has been at the lowest point in a week. The price of n-Heptane has been relatively stable in the last three days. The decline of n-Heptane price is mainly due to the pressure of supply. The high sea freight leads to the accumulation of inventory. Secondly, Junyuan Petroleum Group, as the largest n-Heptane manufacturer in China, needs to actively seize the market demand and break the procurement rhythm of distributors, traders and middlemen. The bargain hunting of customers will gradually break the decline of n-Heptane price. However, in the long-term trend, in January 2022, the n-Heptane market will still face the situation of weak supply and demand. At that time, we still need to pay attention to whether the downstream construction will be limited by policies, whether the new production capacity can be put into operation as scheduled, and the supply and demand of the market before the Chinese New Year.
Chemical News
CNOOC’s CNOOC Gas Power Group Co., Ltd. (hereinafter referred to as “gas power group”) announced on the 21st that it had signed a 20-year, 2 million ton / year long-term liquefied natural gas (LNG) resource purchase and sales agreement with venture global LNG. This is the sixth long-term LNG import agreement between China and the United States this year. Previously, Sinochem, ENN and other enterprises signed a long-term LNG import agreement with the United States. Before this year, there was only one long-term agreement contract being performed between China and the United States.
In addition to the surge in long-term LNG agreements, LNG spot imports have also increased significantly this year. According to customs data, from January to November 2021, the United States exported about 8.26 million tons of LNG to China, surpassing traditional LNG suppliers such as Qatar, Malaysia and Indonesia, and becoming China’s second largest supplier, with the supply proportion increasing from 4% in 2020 to 11%.
Two factors promote the increase of LNG long-term cooperation and trade volume between China and the United States
First, the embodiment of the national strategic will. The LNG long-term agreement signed by China this year mainly comes from Qatar, Russia and the United States. Increasing the LNG import of the United States is conducive to balancing the trade with the United States and reducing the trade deficit.
Due to the tense relations between China and Australia, China announced an indefinite suspension of economic and trade activities with Australia. As China’s most traditional LNG supplier, there is no new long-term agreement contract between China and Australia this year, and Australia’s potential share is basically divided up by the above three countries.
Second, the rich natural gas resources of the United States urgently need to be exported. The EIA predicts that the peak natural gas production capacity of the United States will reach 13.9 billion cubic feet / day by the end of next year. In terms of infrastructure, the new sixth production line of Sabine pass and the export terminal of Calcasieu pass will be put into operation at the end of this year and next year respectively to support the large-scale export of LNG from the United States. According to the information released by the U.S. energy information administration, the United States will become the world’s largest LNG exporter by the end of 2022.
Because of the increasing influence of us LNG exports on the global market, more investors have turned to Henry hub to manage the risk exposure of natural gas prices. Henry port natural gas futures contract is a product of Chicago Mercantile Exchange (CME). It takes Henry port, Louisiana, as the delivery place. Here is the intersection of several interstate and intrastate natural gas pipelines and related infrastructure. Natural gas shippers and sellers can use the pipelines here at any time to meet the needs of the Midwest, northeast, Southeast and southeast of the United States Market demand in the southeast and Gulf Coast. As Henry port has important geographical advantages and perfect logistics infrastructure, it is not difficult to understand why Henry port futures contract will become the price benchmark of the natural gas market.
Shipping Information Hotspot
At the end of 2021, the demand for logistics remained strong. With the global supply chain congestion, continuous interruption and COVID-19, Maersk cautiously expects that the freight outlook will be more optimistic at the beginning of next year.
At the end of 2021, the demand for logistics remained strong. With the global supply chain congestion, continuous interruption and COVID-19, Maersk cautiously expects that the freight outlook will be more optimistic at the beginning of next year.
The Chinese Lunar New Year holiday is coming. Some barge services in South China will be suspended, and there may be a freight peak before the festival. The carrier shall also pay attention to the changes in the HS code of import and export commodities.
As the most important festival in China (February 1 this year), the lunar new year will have a certain impact on the global supply chain. In previous years, the lunar new year was the peak season for China’s exports; Influenced by the recent COVID-19 situation, most factories are still closely monitoring the epidemic trend, especially the local government’s guiding policies, so as to determine the corresponding production plan and holiday arrangement. It is expected that the official will give clearer guidance by January. Maersk expects that the freight demand will remain very strong and the freight volume will remain at a high level from December to the lunar new year in 2022. But COVID-19 may still have some impact on the global supply chain.
Prospect of shipping capacity and container condition in the first quarter of 2022
The shipping schedule is delayed and the transportation capacity will continue to be limited. Maersk expects that the shipping space will still be very tight during the whole lunar new year. It is expected that the supply of 40 inch containers will be insufficient, but there will be a surplus of 20 inch containers, especially in Greater China. There will still be a shortage of containers in some areas before the lunar new year, the export market will continue to be saturated, and the overall import demand is expected to remain at a roughly similar level.
Main route trends
Asia to northern Europe: the interruption of transport capacity will still affect the overall transport capacity. At least until the lunar new year, capacity disruptions will still be common. Our goal is to use the advantages of extensive freight network deployment to invest in overtime ships under appropriate circumstances to digest the backlog of goods, so as to maintain agility. We will update the shipping schedule information regularly and inform the estimated arrival time / estimated departure time.
Asia to the Mediterranean: in order to restore the punctuality rate, we will continue to implement the wrong flight strategy in December and January 2022 to further enhance the transportation capacity. During this period, we will also deploy overtime ships to alleviate the capacity gap.
Asia to North America: due to port congestion, transport capacity is expected to continue to decline. We plan to put four overtime ships into operation in December, so as to reduce the impact of air flights. The congestion of North American ports is unlikely to improve in a short time, so customers are advised to appropriately extend the delivery cycle between the estimated arrival time and the actual departure time.
Asia to Latin America: RO ro cargo transportation will be under control. The waiting time at the departure and destination ports is long, which will still bring some pressure on the alignment rate. For x4a route, we are considering suspending the berthing at Busan / Hong Kong port every two weeks to ensure that the ship sails on time from Asia. Ac2 route will be suspended from Yantian or Ningbo, AC6 route will be suspended from Kaohsiung, Ningbo or Shanghai at the origin and Balboa at the destination to avoid further delay of shipping schedule. During the peak period of spring transportation, it is expected that the margin of 40 inch containers will be very tight. Therefore, it is recommended that customers provide loading plans as soon as possible and consider replacing 40 inch containers with 20 inch containers, so as to realize early shipment.
Asia to the Middle East, India and Pakistan: it is expected that the transportation capacity will be very tight. During December and January 2022, fi4 flights will be opened once a week on the east coast of India, and it is expected to resume weekly docking from February.
Asia to Africa: before the lunar new year, the supply of 40 inch containers will be very tight. It is recommended that customers book space in advance and consider 20 inch container as an alternative. There will be a capacity bottleneck in North China.
From Asia to Australia and New Zealand: the waiting time at the port of origin and destination is long, which will still bring some pressure on the transportation capacity, and it will be very difficult to maintain the normal weekly shipping shift.
Oceania export: the supply of 20 inch freezers in the first quarter is still very tight, and this situation is expected to continue until the peak export season in 2022. Customers are advised to use 40 inch freezers to avoid supply chain disruption. The supply of food grade cabinets in Oceania is still very tight, and Australia is expected to have a strong agricultural export season climax. We have suspended short-term transportation reservations for exports to Southeast Asian destinations and fully support the freight transportation of Tanjung Palapas port in the peak season. It is expected that there will be sufficient space for general cargo export from the east coast of Australia to Northeast Asia and greater China.
Imports from Asia: shipping delays and port congestion are expected to persist, especially in Europe and North America. This will have a negative impact on the on-time delivery of goods. The exclusive cherry express route to Chile will be opened in the 51st and 52nd weeks.
Key words: at the end of 2021, logistics demand remained strong. With the global supply chain congestion, continuous interruption and COVID-19, Maersk cautiously expects that the freight outlook will be more optimistic early next year.

Industry News
◎ judging from the US economic data, crude oil prices rose and fell
Recently, the US dollar index has weakened, reaching 96.09 on December 27, down 0.50% from December 17. The decline of the dollar mainly stems from: on December 20, Goldman Sachs Group lowered its forecast for U.S. economic growth because Democratic Senator manqin said he would not support the core content of President Biden’s economic agenda, that is, the $2 trillion tax and expenditure plan. Manchin’s statement actually killed the Democratic Party’s plan to pass the bill called build back better. Economists at Goldman Sachs said that if the bill could not be passed, it would have a negative impact on U.S. economic growth and would make the U.S. economy face the dilemma of slowing down in 2022. The weakening dollar supported the rise of crude oil prices to a certain extent.
◎ domestic LNG price in terms of apparent consumption
Affected by the epidemic situation, the comprehensive statistics of domestic apparent natural gas consumption from January to February 2020 is 52.7 billion cubic meters. Without splitting, the annual apparent natural gas consumption in 2020 is 320.38 billion cubic meters. Except for the epidemic situation at the beginning of the year and the Spring Festival factors, it is relatively stable throughout the year and increases in the heating season. There will be great changes in 2021. Although the overall consumption increases greatly, the consumption growth rate is unstable. As of October 2021, the apparent consumption of domestic natural gas totaled 302.893 billion cubic meters, an increase of 24.51% over the same period last year. And this year, the apparent consumption in October near the heating season decreased by 2.34% compared with September. The reason is that under the demand expectation and supply guarantee requirements of this year’s heating season, the domestic natural gas reserve work is carried out in advance, and the overall reserve is relatively sufficient. With the promotion of carbon peak and carbon neutralization, the strengthening of environmental protection work by local governments greatly limits the industrial demand, so the demand shrinks near the heating season.
◎ needle coke market summary in November
In November 2021, the import volume of needle coke was 20900 tons, an increase of 11% month on month. Among them, oil measures are 8700 tons, accounting for 41.6%, and coal measures are 12200 tons, accounting for 58.4%. From January to November 2021, the cumulative import volume of needle coke is about 205400 tons, and the oil series is 97500 tons, accounting for 47%. Coal measures account for 10.79%, accounting for 52%
◎ liquefied gas: the market rebounded at a low level after ether appeared on the positive support of supply and demand
The supply of some oil producing countries has decreased and the market demand prospect has been better supported. The international crude oil trend is strong, which has obvious positive support for the relevant industrial chains in the region. However, as the end of the year is approaching, there is a certain demand for inventory discharge by enterprises, and the market atmosphere tends to be conservative. It is expected that the market will maintain stability in the short term, and the power for both rise and fall is insufficient. After the year or due to the centralized replenishment of downstream goods, The market has a “good start” again, but under the influence of policy, there is uncertainty. Follow up, pay close attention to the startup and shutdown of upstream and downstream devices.
◎ game between cost and demand, stalemate in polyester filament Market
With strong cost support and weak demand as a foregone conclusion, polyester filament needs to pay more attention to its own fundamental data. As we all know, the load of direct spinning factories in the Spring Festival is higher than that of looms, so the inventory of polyester filament factories from January to February is expected. According to the market understanding, the inventory of some polyester filament factories has been at a high level. Near the Spring Festival, the factory or machine price exchange is not ruled out. At this time, polyester filament is in a shock downward trend in the game of cost and demand, or dragged down by demand.
◎ the supply of polyester bottles and chips is reduced, and the spot in the market is still tight
From the order receiving situation of polyester bottle chip manufacturers, the order receiving amount of the factory has decreased recently. Since mid September, due to the influence of dual control, some production enterprises have limited operation and reduced supply, and the spot circulation of polyester bottles and chips shows signs of tightening. In addition, the increase in foreign trade shipments has exacerbated the tense atmosphere of spot circulation. The large downstream soft drink manufacturers will advance the procurement cycle and the centralized purchase time to November. In the fourth quarter, according to the past performance, the demand is off-season, and the bottle chip factory is overhauled during this period. However, this year is different from previous years. The off-season is “not light”, and the demand side makes collective efforts. As a result, the polyester bottle chip factory has no spot to sell and can only sell far month futures. Last weekend, a 600000 ton unit of a large factory in East China was overhauled as planned, the supply was further reduced, and the price of polyester bottles and chips rose steadily.

the price of n-heptane plunged by 6.58 percentage
HeptanesPentane Blends

Foam Blowing Agent prices fell and n-Heptane prices plunged – 12/28/2021

by David Zhang, Sales Manager at Junyuan Petroleum Group

Today, the price of n-Heptane plunged by 6.58 percentage points. The price of pentane blowing agent increased by 0.85% on December 24, and then decreased by 0.84% on December 28. The continuous rise and fall of prices has always been the characteristic of foaming agent products, and the market price fluctuates too much due to the cost of raw materials.

The recent favorable factors in the crude oil market have the upper hand, and the crude oil price may maintain a strong trend and continue to operate at a relatively high level.

Pentane Foaming Agent

by David Zhang, Sales Manager at Junyuan Petroleum Group

Pentane foaming agent is extremely flammable. Its vapor and air can form an explosive mixture. It is very easy to burn and explode in case of open fire and high heat Strong reaction with oxidant and even combustion Liquid is lighter than water and insoluble in water. It can drift and spread to a distance with water and cause combustion in case of open fire In the fire scene, heated containers are in danger of explosion.

The new technology of hydrobenzene removal with pentane foaming agent is to remove impurity benzene from raw materials under mild conditions (temperature 130 ~ 150 ℃, pressure 0.3 ~ 0.5MPa) and nickel catalyst. This process is used in the production of blowing agent of Junyuan Petroleum Group. After the application of this technology, the benzene content in pentane blowing agent is reduced from 300mg / kg to 5mg / kg, which has good economic and social benefits.

Pentane Used as Foaming Agent

by David Zhang, Sales Manager at Junyuan Petroleum Group

Pentane as foaming agent is mainly used to foam polyurethane and styrene. In pentane foaming agent, pentane is mainly n-pentane and isopentane, and when the proportion reaches more than 99%, it can be used as styrene foaming agent, and the finished product is EPS.

In addition, n-pentane can be used for foaming of building plates. The main purpose of making polyurethane foaming agent is cyclopentane, which is mainly used for foam in the refrigerator door. When you go home, you can see the label of cyclopentane on your refrigerator. This is mainly due to the cavitation of ozone layer before foaming, but later replaced by 141b, but it is still polluted. Pentane will not be cleaned. Pentane has a low density of about 0.62, which is flammable and volatile. As a foaming agent, it uses its volatile characteristics to leave small holes in styrene or polyurethane. It should belong to physical foaming without chemical reaction. Up to now, EPS foaming with pentane has been a mature system, while polyurethane foaming with cyclopentane is still developing. Because China pays close attention to industrial safety, few manufacturers can change the foaming agent from 141b to cyclopentane for polyurethane, mainly large refrigerator factories such as Haier and Hisense.
