Pentane blowing agent: market supply and demand changes from raw material prices

Since 2022, affected by the strong rise in the crude oil market, the price of Domestic Topping oil has risen as a whole, and the profits of downstream pentane foaming agent manufacturers once entered a negative range. In the middle of March, the crude oil began to fall after rising, the price of Domestic Topping oil began to decline, the profits of pentane blowing agent manufacturers improved, and the manufacturers began to operate one after another.

Taking Shandong as an example, it can be seen from the above figure that since 2022, the prices of topping oil and pentane foaming agent in the region have increased. However, from January to February, the price of raw materials has increased too fast, which has been higher than the price of foaming agent products for a long time. Considering the freight of raw materials, the processing cost of devices and other factors, the device has suffered obvious losses. The foaming agent factories in Dongying have shut down one after another, and the supply has declined. At present, the total capacity of pentane units in the Chinese market is about 3million tons, the daily theoretical supply is about 8200 tons / day, and the actual daily output is about 5800 tons. By the middle of March, it was more difficult to find goods downstream.

However, in the middle of June, the domestic refined oil market demand was poor. In particular, the epidemic situation in Shandong repeatedly led to the upgrading of management and control, many regions entered the state of home isolation, and the reduction of travel further weakened the gasoline consumption. As of June 29, the national VI 92. It is understood that the unit of Daqing Oilfield fine chemical industry was restarted on June 12, Dongying Liangxin Petrochemical Technology Development Limited Company resumed construction around March 15, and Shida Changsheng plans to resume construction on March 15, resulting in an increase in market supply.

As for the future market, the supply of pentane blowing agent in the Chinese market will remain stable from mid to late March to June. In terms of raw materials, there are certain guidelines on the news. The market has digested in advance the benefits of supply tightening brought about by the overhaul of Huaxing, Changyi, Zoje, etc. at present, it is mainly supported by downstream demand. By early April, there was a small and long Tomb Sweeping Day holiday in China. Although the epidemic situation has been repeated to a certain extent, there are still some goods in the domestic gasoline market, supporting the acceleration of raw material shipment and supporting the pentane foaming agent market. The downstream EPS market of foaming agent is expected to be better as the temperature warms up. Overall, the pentane blowing agent market maintained good supply and demand from mid March to June.

The Prices of Pentanes Fell

03/16/2022 Today, the prices of n-Pentane and Pentane Blowing Agent products collectively fell, from – 1.15% to – 2.17%.Pentane can be obtained from catalytic cracking and thermal decomposition of natural gas or petroleum. Due to different refining degrees, it often contains isomers of C5 Hydrocarbons, hydrocarbons with similar boiling points such as METHYLCYCLOPENTANE, and impurities such as unsaturated compounds, water and sulfur-containing compounds.

Pentane foaming agent is mainly composed of n-pentane and isopentane, and 9 products are composed according to different components. The models are F1, F2, F3, F4, F5, F6, F7, F8 and F9, as shown in the table below. 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 occurs when contacting with oxidant, even causing 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.

Application of Pentane Blowing Agent
Pentane is the main foaming agent used to produce polystyrene foam and other foams. Generally, mixtures of N -, I – and more and more cyclopentane are used for this purpose. Because of its low boiling point, low cost and relative safety, pentane is used as the working medium of geothermal power stations. It is also added to some refrigerant mixtures.
Pentanes are relatively cheap and are the most volatile alkanes that are liquid at room temperature, so they are usually used as solvents that can be easily evaporated in the laboratory. However, due to their nonpolarity and lack of functionality, they can only dissolve nonpolar and alkyl rich compounds. Pentane is miscible with most common nonpolar solvents, such as chlorocarbons, aromatics and ethers. They are also often used in liquid chromatography.

General pentane (hereafter, pentane) is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-pentane (the most important isomer), isopentane, and neopentane. n-Pentane is a constituent of crude oil and a component of the condensate from natural gas production. It is primarily obtained by fractional distillation of a petroleum stream (generally light virgin naphtha) obtained from the processing of crude oil. n-Pentane is used as a component of gasoline blends, as an aerosol propellant, in low temperature thermometers, as a blowing agent for foams (e.g. expandable polystyrene (EPS) and polyurethane (PUR)), and as a solvent (EU 2003). Isopentane is also used as a blowing agent, and neopentane is used in the manufacture of butyl rubber (ACGIH 2001).

Cyclopentane is a FLAMMABLE LIQUID and a FIRE HAZARD. IDENTIFICATION Cyclopentane is a clear liquid. It is used as a laboratory reagent, a solvent, and as an extraction agent in the paint and shoe industries. REASON FOR CITATION * Cyclopentane is on the Hazardous Substance List because it is cited by ACGIH, DOT, NIOSH, NFPA and EPA.

2-METHYLBUTANE (ISOPENTANE)†. Watery colorless liquid with a gasoline-like odor. * All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details. As Pentane; there is no specific OSHA PEL for 2-Methylbutane. CAS #: 78-78-4 Formula: C₅H₁₂

A blowing agent blend for making polyolefin foams comprising isopentane and at least one co-blowing agent The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof The blowing agent blend comprises less than about 99 mol % isopentane.  A polyolefin foam structure prepared by the process comprising: melting a thermoplastic polyolefin polymer, dissolving an effective amount of a blowing agent blend in the polyolefin polymer, the blowing agent blend comprising less than about 99 mol % isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, forming an extrudate, transferring the extrudate to an expansion zone, and permitting the extrudate to expand in the expansion zone to produce the polyolefin foam structure, the polyolefin foam structure being a substantially closed-cell and dimensionally-stable structure. A process for making a polyolefin foam structure comprising: melting a thermoplastic polyolefin polymer, dissolving an effective amount of a blowing agent blend in the polyolefin polymer, the blowing agent blend comprising less than about 99 mol % isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, forming an extrudate, transferring the extrudate to an expansion zone, and permitting the extrudate to expand in the expansion zone to produce the polyolefin foam structure. A blowing agent blend for foaming low density polyethylene foam consisting essentially of isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, and wherein the blowing agent blend includes from about 10 to about 99 mol % isopentane and the remainder consists essentially of the co-blowing agent. The blowing agent blend of claim above, wherein the co-blowing agent includes at least one physical co-blowing agent, the at least one physical co-blowing agent being ethane, n-propane, n-butane, isobutane, cyclopropane, nitrogen, argon, carbon dioxide, sulfur hexafluoride, nitrous oxide, dimethyl ether, 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1,2,2-tetrafluoroethane (HFC-134), 1,1,1,3,3-pentafluoropropane (HFC-245fa) or combinations thereof.

Presently, physical blowing agents more commonly used for making low density polyethylene (LDPE) foams are hydrocarbons such as isobutane or blends of isobutane and n-butane. Other hydrocarbons such as ethane and propane have been used more recently in making LDPE foams. The ability of isobutane, n-butane, propane, ethane and combinations thereof to give stable, low density foams depends on factors such as desirable solubility in low density polyethylene, and the ability of gas permeation modifiers to slow down the escape of such blowing agents. The resultant foam article (e.g., a sheet) using such blowing agents is frequently produced with at least some corrugation. Corrugation occurs when the radial rate of expansion is higher than the radial space available for the foam as it exits the die. Corrugation may be reduced to a certain extent by optimizing the foaming process and apparatus used in forming the foam with these blowing agents, but a low degree of corrugation or visible corrugation lanes often remain. The corrugation becomes more pronounced when a fluid with a very low boiling point (e.g., ethane or propane) is (a) used as the sole blowing agent or (b) present in an amount greater than about 5 mol % with a higher boiling fluid (e.g, isobutane). Corrugation also tends to occur more frequently in sheets (thickness of up to about ½ inch) as opposed to planks (thickness of greater than about an inch), and the degree and magnitude of corrugation increase as the foam density decreases. According to one embodiment of the present invention, a blowing agent blend for making polyolefin foams comprises isopentane and at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof. The blowing agent blend comprises less than about 99 mol % isopentane. The polyolefin foam may be a low density polyethylene foam. The blowing agent blend may consist essentially of isopentane and the co-blowing agent in which the blowing agent blend includes about 10 to about 99 mol % isopentane with the remainder consisting essentially of the co-blowing agent.

A blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or phase transition, such as polymers, plastics, and metals. They are typically applied when the blown material is in a liquid stage. The cellular structure in a matrix reduces density, increasing thermal and acoustic insulation, while increasing relative stiffness of the original polymer.

Blowing agents are additives used in the manufacture of foamed plastics, which have the advantage of lightness, contribute to material and cost savings, and are distinguished by the fact that they are thermally insulatingBlowing agents usually create fine and regular cellular structures during polymer processing.

The global warming potential (GWP) of the blowing agents used to manufacture insulation products like polyiso insulation can be an important consideration when assessing each product’s environmental impacts. Blowing agents function to increase the final thermal resistance or R-value of foam insulation, and also help to facilitate the manufacturing or foaming process.  

Manufacturers of laminated insulation products in North America use #pentane or #pentane #blends in their production processes. Pentane is a hydrocarbon with zero ozone depletion potential (ODP) and low-GWP. Manufacturers have utilized pentane technologies in product formulations for over 20 years.

Pentane has a GWP value of less than 10, which means that insulation products produced and sold in North America comply with climate regulations that limit the manufacture or installation of products produced with higher-GWP substances (including products manufactured with hydrofluorocarbons (HFCs) or blends thereof). Therefore, architects and contractors can continue to specify insulation products manufactured by PIMA members with confidence in both the industry’s performance and environmental scorecard.

When it comes to blowing agents, a controlled foam structure makes your production process go a lot smoother

Not only do blowing agents expand up to 60 times in volume, they also provide:

  • highly controlled foaming
  • closed, uniform cell structure
  • guards against water penetration
  • create internal pressure to combat shrinkage.

What is EPS

Polystyrene is one of the most widely used kinds of plastic. It is a polymer made from the monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum by the chemical industry. Polystyrene is a thermoplastic substance, it melts if heated and becomes solid again when cool.

Polystyrene is most commonly found in three forms. Rigid Polystyrene (PS), Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS).

Rigid polystyrene has many applications including disposable cutlery, cd cases, video/casette casings, components for plastic model toys as well as some margarine and yoghurt containers.  Extruded polystyrene foam has good insulating properties making it important as a non-structural construction material.  XPS is sold under the trademark Styrofoam by Dow Chemical, however this term is often used informally for other foamed polystyrene products.

How to produce foam?

Expandable Polystyrene / EPS:

This is PS Foam that uses Pentane gas (C5H12) as the blowing agent. During the material production process called “Polymerisation” the polystyrene resin granules impregnated with the blowing agent. EPS production processes begin in the pre-expansion process where the EPS bead will expand by the heat of steam usually 50 times in volume. The next step in the process is moulding process where expanded foam bead will be heated again with steam then they expand further until they fuse together, forming as foam products.

Expandable Polystyrene / EPS:

There are mainly 2 types of EPS moulding machines;

  • Shape moulding machine that produce various shapes of foam products according to the molds such as icebox, helmet and packaging foam.
  • Block moulding machine that produce block foam and sheet foam Expanded EPS foam bead contains 98% air per volume, only 2% is plastic. This make EPS foam very light weight, has low thermal conductivity because air is the best insulation, high compressive strength and excellent shock absorption. These properties make EPS to be ideal material for packaging and construction.

Polystyrene Paper (PSP):

This is a PS Foam which is produced by extruding process as another plastic. Production process start when put polystyrene resin pellets into the extruder that heated by electric. Foaming process occur at the end of extruder where the blowing agent, butane (C4H10) gas react with the melt plastic then become foam. The melted polystyrene foam is then extended as sheet then rolled as paper roll, that is why it is commonly known as “Polystyrene Paper”. The polystyrene foam sheet or polystyrene paper can be produced as many shape according to the mould by thermal forming process such as food tray, cups, bow, and food box.

There’s no any CFC’s in PS foam

Both EPS and PSP contain 95 -98 % air another 2-5% is polystyrene which is pure hydrocarbon. CFC’s is Chlorofluorocarbons which is totally different in its chemical structure from polystyrene. CFC’s has very low blowing point and uneasy to be maintained in EPS beads. Therefore, EPS Foam never use CFC’s at any stage of its production. The blowing agent used since EPS Foam was first introduced in 1952 by BASF  is Pentane gas which, does not contain any chlorine atoms as CFC’s. PSP Foam in the beginning used CFC’s as blowing agent. In the past two decades CFC’s are gradually phased out from plastics and refrigerator industries. PSP moulders in Thailand already use Butane (C4H10) as the blowing agent since the last 15 years. Butane gas is the gas that we use at home for cooking. The blowing agents that use in producing PS Foam are Pentane and Butane, which are pure hydrocarbon as polystyrene. They belong to the same chemical family, the paraffin series as methane, ethane, and propane gas.

How to manage the EPS foam waste

Apart from recycling by melting and compacting, there are many ways to manage the EPS waste as the followings:

  • Crush in to small particle and mix with soil. Foam waste will improve ventilation in the soil, organic substances in the soil will become easier the humus.
  • Mixing the crushed bead with cement to reduce the weight and increase insulation properties.
  • Combustion at 1000 C with sufficient air supplies in to generate heat. Burning EPS require no any additional fuel, in fact EPS can replace the fuel normally required for combustion, l kg of EPS saves 1 kg = 1.2 – 1.4 Litre of fuel oil.

The Recycling of PS:

Since both EPS and PSP Foam are made of Polystyrene, which is thermoplastic, so that it will become again a polystyrene plastic when recycled. AMEPS members recycle both EPS and PSP Foam by first crushing into small particle then melting or compacting it. Melting can be done by heated roller, disk or screw extruders, where the regrind scraps is heated usually by electrical power for some time above the melting temperature. Compacting can be done by rotary compactors where pressure and frictional force create heat below melting temperature to soften the regrind scraps for only few seconds. This method also called “agglomeration”.PS pallet from recycled foam will be produced in various kinds of plastic products e.g. video and tape cassette and ruler. The other way to reuse EPS Foam is to mix the regrind beads with the new expanded bead for re-production in moulding process.
