DESCRIPTION

—— Isoprene——

Molecular Formula： C₅H₈

Product Properties：

Luhua isoprene is manufactured from the C5 feedstocks derived from petroleum cracking to produce ethylene. The product is a colorless or slightly colored transparent flammable and explosive liquid. Specific gravity: 0.6806; Melting point: -147.7°C; Boiling point: 34.1°C; Flash point: -53.89°C; Auto-ignition point: 220°C; Explosive limit (V/V): 1.5~9.7%.

Packaging：In bulk, container tanks or 200L drums.

Storage：Store at low temperatures and refrigerate in summer (lower than 15°C). Mode of transportation:Transported as Class 1 dangerous goods. Bulk goods can be transported in tankers

Product Application：

Isoprene is an important C5 diolefin that can be polymerized to synthesize rubber, plastics and other synthetic materials as well as terpenes compounds. It has a typical conjugated double bond structure which is chemically active, it can also be used in the synthesis of fragrances, pesticides, drugs and other fine chemicals through various chemical reactions.
