In recent months, the price of n-Pentane in China has seen a significant decline. This downward trend can be attributed to several key factors: Despite these challenges, there is optimism for a potential recovery in the future, driven by smooth logistics and increased purchases during upcoming festival seasons. However, the current market conditions continue to exert downward pressure on n-Pentane prices in China.
With the continuous growth of global demand for clean energy, geothermal power generation, as an environmentally friendly and renewable form of energy, is gradually receiving attention from around the world. This article provides an overview of the development history, global layout, and several major thermal systems of geothermal power generation. Special mention was made of Italy as the world’s earliest country to utilize geothermal power generation, as well as China’s progress in the field of geothermal power generation. In addition, it also introduced the important raw materials provided by Junyuan Oil Group for global geothermal power generation projects.
n-Pentane is an important organic chemical raw material, with the chemical formula C5H12. This article will provide a scientific introduction to the properties, uses, storage methods, and applications of n-Pentane in the chemical industry.
Choosing between n-Pentane, Isopentane and Cyclopenane depends on the intended use. Here are some general differences between them.
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.
Expandable polystyrene (EPS)
Revolutionary patented polystyrene production method
Expandable polystyrene (EPS) consists of polystyrene micro-pellets or beads containing a blowing agent and other additives for foaming. We have developed a continuous production process in which the blowing agent is directly injected into the melt, combined with subsequent underwater pelletization.
commercial EPS is manufactured with the addition of a blowing agent, typically a chlorinated hydrocarbon or a low-boiling petroleum-derived agent with the presence of pentane. These substances are highly flammable; by reducing the amount of flame retardant due to the addition of gypsum, they ignited during the flame propagation test, increasing the burn rate of the GPS.
