How We Ensure Timely Delivery of Samples of Solvents to Our Global Customers?

As a leading chemical company, at Junyuan Petroleum Group we are committed to providing high-quality and innovative products to our customers around the world. However, delivering chemical samples to different countries and regions is not a simple task. It requires careful planning and execution, as well as compliance with various laws and regulations. To ensure the safety and legality of our sample shipments, we follow these steps: – We identify the type and hazard level of our chemical samples, and whether they need any special permits or certificates. – We choose the appropriate shipping service and mode of transportation, such as air, land or sea, that meet the international or domestic transport rules. – We use proper packaging materials and labels, to prevent leakage, damage or mishandling of our samples. – We fill out complete and accurate shipping documents, including the information of the recipient and the sender, as well as the name, quantity, hazard level and other relevant information of our samples. – We hand over the shipping documents and samples to the shipping service provider, pay the corresponding fees, and track the shipping status. By following these steps, we can ensure that our samples reach our customers in a timely and efficient manner, and that we maintain our reputation as a reliable and trustworthy partner. We are always ready to serve our customers with our best products and services. Some of our most popular products are n-Pentane, Isopentane, Cyclopentane, Blowing Agents, n-Hexane, Isohexane, n-Heptane, n-Butane and Isobutane. These products are widely used in the production of insulation materials, such as Polyurethane (PU) and Polystyrene (PS) foams. They have different properties and advantages, depending on the application and the desired insulation performance¹². For example, Cyclopentane offers an extremely high and lasting insulating effect, as it remains partially in the cells of PU and PIR foams after foaming¹. N-Pentane and Iso-Pentane have a lower insulating effect than Cyclopentane, but they are more stable and the individual cells are firmer and finer². Blowing Agents are mixtures of different Pentanes, which can optimize the costs and foam properties¹. We test these products in our state-of-the-art laboratories, to ensure their quality and safety. We also customize the products according to the specific needs and preferences of our customers. For example, we can adjust the purity, viscosity, boiling point, and flash point of the products, to suit different applications and climates. The typical amount of samples that our customers request is around 250 milliliters, but this may vary depending on the product and the customer’s requirements. We always try to accommodate the requests of our customers, as long as they are reasonable and legal. We also provide technical support and guidance, to help our customers use our products effectively and efficiently.

What is the use of n-Heptane UV absorption?

Heptane is an organic compound with the molecular formula C7H16, which is a type of alkane. It is a colorless liquid with a slight gasoline smell, flammable, insoluble in water, but soluble in organic solvents.

Heptane has some industrial applications, such as being used as a solvent, fuel, or raw material for synthesizing other chemicals.

Heptane can absorb ultraviolet rays, so it can also be used as a UV absorber, such as in sunscreen or plastic. The function of UV absorbers is to prevent UV damage to the skin or materials, such as sunburn, aging, discoloration, or degradation.

Introduction to Malaysia ASEAN Free Trade Certificate of Origin (FORM E)

Introduction to Malaysia ASEAN Free Trade Certificate of Origin (FORM E)

Malaysia certificate of origin, also known as China’s certificate of origin for export to Malaysia, can also be called Malaysia ASEAN certificate of origin Form E. Malaysia ASEAN certificate of origin Form E is issued by China entry exit inspection and Quarantine Bureau and consists of one original and three copies. The main purpose of applying for ASEAN certificate of origin Form E for export to Malaysia is to obtain the tariff preference of the Malaysian authorities when the goods are imported into Malaysia, so as to enable the smooth customs clearance of this batch of goods.

The Malaysian certificate of origin Form E cannot have double headers. The header of the trader or factory can only be displayed under the description of the goods in the seventh column of the Form E certificate of origin, and cannot be displayed in the exporter column in the first column of the certificate of origin. For export declaration, the header of the trader or factory can be used normally.

1. Consignee name and address cannot be bank name.

2. The departure date, ship name, port of departure and port of destination must be correct and consistent with the bill of lading.

3. The amount on the certificate of origin must show FOB amount.

Malaysian import tariff system

As a member of the world trade organization, Malaysia’s tariff level is generally low. Although the tariff rate of most items is lower than 25%, the value range of tariff rate is very wide. The tariff on basic food is very low, no more than 5%. The average tax rate for major goods is about 5%. The average tax rate of intermediate products and transportation equipment is less than 20%. The tax rate of consumer goods is higher, some as high as 60%. The tariff rate for high priced motor vehicles is higher than 100%. In short, of its total of about 600 imported items, only 91 have a tariff rate of more than 50%. As a member of the ASEAN Free Trade Area (AFTA) under construction, Malaysia’s tariff reduction will implement the “generally effective preferential tariff” (CEPT) plan in the AFTA regulations. The main imported products of Malaysia are divided into three categories. The first category is raw materials and means of production, including electronic components, textiles, plastics, machine parts, oil, chemical fertilizers, pesticides and food, accounting for 42.6% of the total import volume; The second category is mechanical equipment, including metal products, mechanical transport equipment, electronic instruments, heavy machinery and telecommunications equipment, accounting for 34.5% of the total import volume; The third category is daily necessities, including motorcycles, bicycles, jewelry and food, accounting for 21.9% of the total imports. All imported goods from Malaysia shall be subject to a 5% surcharge based on CIF value. Some basic goods such as fish, Cereals, salt, petroleum products, rubber, paper and printed products are exempt from additional tax. Excise taxes shall be levied on beer, alcohol and other beverages, cigarettes, gasoline, mineral oil and sugar, tires, cards, air conditioners, batteries, TV receivers, motor vehicles and motorcycles, matches and other commodities at ad valorem or specific volume.

Cyclopentane in reagent bottle

A Blowing Agent for the Polyurethane Foams

Cyclopentane – A Blowing Agent for the Polyurethane Foams
Cyclopentane is usually used as a new, more environmentally friendly insulation material in the manufacture of select refrigerators and freezers.
Cyclopentane is a blowing agent for the polyurethane foams that are used to insulate refrigerators and freezers.
Unlike some other chemicals used to insulate refrigerators, cyclopentane does not contain hydro-fluorocarbons (HFCs). Using cyclopentane results in significant reductions in equivalent CO2 emissions.
The most common foam-blowing agents currently used in the U.S. are R134a and R245fa. These industry-standard insulations can have a global warming potential (GWP) as high as 1300 (134a) and 950 (245a). In contrast, the foam-blowing agent cyclopentane has a GWP of approximately 10. When it comes to GWPs, the lower the number is, the better it is for the environment, so cyclopentane is clearly the more environmentally friendly choice.
Cyclopentane increases the efficiency of the insulation foam by approximately 4 percent over the R134a foam currently used in most refrigeration products.
Cyclopentane has been very popular as a blowing agent in Europe since the early 1990s, but the cost of retrofitting existing production facilities and the lack of U.S. regulations restricting the use of HFCs has delayed implementation in the U.S. However, there are other manufacturers currently selling refrigerators in the U.S. that use cyclopentane.
Compared to other insulating foams, cyclopentane is competitively priced and relatively easy to produce.
Like many gases, in its pure form, cyclopentane is a highly evaporative and flammable material. However once foamed, the unit is no more hazardous than a unit foamed with other blowing agents. As with any of our manufacturing processes, we’ve integrated a wide variety of redundant engineering and operational safeguards.

Common questions about cyclopentane
Q: What is this new material being used in the foam insulation?
A: The new material is called cyclopentane, a highly evaporative gas that is used to apply the foam insulations in refrigeration units.
Q: What is cyclopentane?
A: Cyclopentane is a blowing agent for the polyurethane foams that are used to insulate refrigerators and freezers.
Q: What are the benefits of using cyclopentane instead of other materials?
A: From an environmental perspective, unlike some other chemicals used to insulate refrigerators, cyclopentane does not contain hydro-fluorocarbons (HFCs). Using cyclopentane results in significant reductions in equivalent CO2 emissions.
Q: What foam-blowing agents are most commonly used in the U.S.? How is cyclopentane different?
A: The most common foam-blowing agents in the U.S. right now are R134a and R245fa. These two industry-standard insulations can have a global warming potential (GWP) as high as 1300 (134a) and 950 (245a). Comparatively, the foam-blowing agent cyclopentane has a GWP of approximately 10. When it comes to GWPs, the lower the number is, the less adverse impact on the environment, so cyclopentane is clearly a better choice.
Q: Are there significant insulating advantages, as well?
A: Yes, cyclopentane is approximately 4 percent more efficient than the R134a foam we currently use in most of our products.
Q: Do other refrigerators available in the U.S. market use cyclopentane?
A: There are other manufacturers currently selling refrigerators in the U.S. that use cyclopentane.
Q: Why hasn’t cyclopentane caught on in the United States?
A: It has been very popular as a blowing agent in Europe since the early 1990s, but the cost of retrofitting existing production facilities and the lack of U.S. regulations restricting the use of HFC’s has delayed implementation in the U.S.
Q: Is it more expensive than other insulating materials?
A: It is competitively priced and relatively easy to produce.
Q: Is it dangerous?
A: Like many gases, in its pure form, cyclopentane is a highly evaporative and flammable material. However once foamed, the unit is no more hazardous than a unit foamed with other blowing agents. As with any of our manufacturing processes, we’ve integrated a wide variety of redundant engineering and operational safeguards.

Why is n-Hexane used for edible oil extraction?

Why is n-Hexane used for edible oil extraction?

The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-Hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. Unlike other solvents, hexane has certain properties that make it the ideal choice for oil extraction processes. Hexane can extract more oil from oilseeds compared to ethyl acetate and ether With its low boiling point, hexane can retain its liquid states even in cold climates.

The distillation range of n-Hexane is short, and the volatilization of harmful substances is relatively clean and thorough, so that the nutritional components of vegetable oil are not destroyed by high temperature, which improves the safety of edible oil, reduces the leaching consumption and residue of edible oil in production, has a high oil production rate, and is convenient for industrial scale production. Hexane is an organic solvent with good viscosity. It is usually used in rubber food, pharmaceutical, perfume, shoe making, adhesive tape, ball making, grinding, leather, textile, furniture, paint industries, or dilution, or cleaning solvent, or viscose.

In addition, it can also be used as a solvent for extracting seed oil (such as soybean oil, cottonseed oil, flax oil, peanut oil, safflower oil, etc.); It can also be used as a raw material for manufacturing polymers; Such as polypropylene and polyethylene.

Solvent extraction technology is a continuous edible oil extraction equipment, which uses the solubility of n-Hexane and oil to improve the oil content through soaking and spray. Solvent extraction technology can be used to extract oil from most oilseeds. The high oil content oilseeds such as rapeseed, peanut, cottonseed and sesame are extracted by pre pressing solvent, and the low oil content oilseeds are extracted by direct solvent.

Food grade n-Hexane as solvent for vegetable oil extraction

The main advantage of using n-Hexane as extraction solvent to prepare edible oil is low residual oil. In addition, there are eight advantages:

1. In the detection of the final edible oil products, the sulfur and benzene content in n-Hexane is very low, which is almost impossible to detect, and more in line with the international health detection standards.

2. The distillation range of n-Hexane is 63 ℃ – 71 ℃, and the dissolution rate is small.

3. The recovery temperature of n-Hexane is low and the energy saving effect is obvious. Moreover, it is of great benefit to improve the quality of oil products, and the color will be better. The acid value and peroxide in the oil can be reduced to improve the refining yield.

4. The content of n-Hexane is increased, the extraction capacity is improved, and the processing capacity of the device is also improved.

5. n-Hexane has good compatibility with oil and can reduce the residual oil in the filter cake. Increase the output of oil and improve the efficiency of enterprises.

6. The use of n-Hexane can reduce the drying temperature during the cake recovery process, reduce the direct steam supply, and thus reduce the dust intrusion of the condensation recovery system. Prolong the life cycle of the condenser.

7. Due to the extremely low sulfur content in n-Hexane, the corrosion of the system is reduced and the service life of the equipment is prolonged.

8. Reducing the operating system temperature after using hexane can reduce the reduction crystallization of unstable substances in the plant and improve the utilization rate of the whole system.

It can be seen from the above description that n-Hexane is the best choice in vegetable oil plants, which is also the reason why solvent extraction plants are becoming more and more popular in large vegetable oil production plants.

Hexane and oils work quite well together, which makes hexane an ideal solvent for oil extraction. Oil extraction requires fats to be soluble in a material, and hexane is a great match because it allows the oils to dissolve and separate from the original oilseed plant. The solvent extraction plant is the best solution for the project with a capacity of more than 30 tons / day. Because the residual oil amount is more than 5% for the press method and less than 1% for the solvent extraction method. The crude powder extracted by solvent extraction can be widely used in food raw materials with high protein content and high quality because of its low temperature.

We have the latest equipment and technology for the strict checking of raw material at the initial stage only. We ensure that prior to manufacturing the material is checked on the grounds of quality. As quality is our topmost concern, we give maximum priority to the stringent checking of the entire range of products. Junyuan Petroleum Group provides the food grade hexane for edible oil extraction and for pharma industries.
