Major Applications: ?betway888 is a very important C5 diene(s), and can be used to make, via polymerization, synthetic rubber, plastics and terpene’s compounds. It has typical conjugated double bond with reactive chemical nature, so that it can synthesize per?
Packing: Bulk or 200L drum. ?
Storage: Stored at low temperature, especially in summer, below 15, 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, package should be sealed, better to fill it with N2. to isolate the air. Stored separately from oxidizer or acid,. ?
Transportation: As hazardous matters class I, the bulk can be handled by tank truck.. ?
