Application

Isoprene can be used to make, via polymerization, synthetic rubber, plastics and terpene compounds. Also through a variety of chemical reactions can be used to synthesize spices, pesticide, medicine and other fine chemical products, such as, linalool, vitamin E, etc.

Packing: Bulk

Storage & Transportation

Storage: Stored at low temperature and well ventilated place, kept away from open fire, heat source and direct sunlight. The product is not suitable for long term storage due to its sensibility to polymerization. Avoid contact with the materials such as oxidants, acids, halogens, etc.

Transportation: As hazardous matters class I, the bulk can be handled by tank truck.

Uses :

Isoprene is a very important C5 diene(s), and can be used to make, via polymerization, synthetic rubber, plastics and terpene’s compounds.
