Description

factory supply high quality refrigerator Cyclopentane/N pentane/ Isopentane with best quality and price

Cyclopentane is a colorless, transparent, pungent liquid. Insoluble in water and miscible with alcohol, ether, ketone and benzene. Cyclopentane is a kind of low toxicity, which can stimulate the skin mucous membrane. It can damage the skin when exposed in large amounts and has a slight anesthetic effect when exposed in high concentration.

To use

Now it is mainly used in the field of polyurethane industry and the field of insulating materials for refrigerator and freezer. Another main use is to make styrene butadiene rubber solvent. In addition,Cyclopentane can be used as polymerization solvent for polyisoprene rubber, cellulose brewing solvent and comparative samples by gas chromatography.

Storage and transportation

Strictly avoid leakage and vessel damage, pay attention to light loading, avoid static electricity, avoid contact with fire source and strong oxidizer, and adopt cooling measures in high temperature season. The extinguisher USES foam, carbon dioxide, dry powder, sand. Water is not effective in extinguishing fire.
