Cyclopentane is a colorless, transparent liquid with a gasoline-like odor and the chemical formula C5H10; it serves as a blowing agent for rigid polyurethane foam.
With a boiling point of 49.3°C and a flash point of -37°C, cyclopentane is characterized by its low boiling point and high volatility. Its extremely low flash point classifies it as a highly flammable hazardous material, requiring strict control over ignition sources and static electricity during use, storage, and transportation.
Cyclopentane is valued for its versatility, serving as a blowing agent, chemical raw material, solvent, refrigerant, and lubricant. It is a key raw material for the production of eco-friendly products-such as refrigerators and freezers-and is also used in cold storage facilities and pipeline insulation.
Zhonglian Energy supplies cyclopentane with a purity of over 95%, available in tank trucks, ISO tanks, and drums. The product is sold to more than 50 countries and regions worldwide, with a strong track record of repeat orders from customers.
