Molecular Formula: C5H8 The goods is an important monomer of synthetic rubber, its dosage accounted for 95% of the total output of isoprene, mainly used for the synthesis of isoamyl rubber, its production after styrene-butadiene rubber and butadiene rubber and synthetic rubber in the third.Secondly, used as a monomer synthesis of butyl rubber, to improve the butyl rubber vulcanization performance, but very few dosage, isoprene is also used in synthetic resin, liquid polyisoprene rubber, etc.Also used in the manufacture of pesticide, medicine, spices, adhesives, etc.
