Application: It is used as a general synthetic rubber, can be mixed use by natural rubber, butyronitrile rubber and butyl rubber. It is widely used to rubber products such as tire surface, various kinds of rubber hoses, rubber belt, sealing ring and sole. It can also be used in high cold resistance products and used as shockproof materials.
Package and storage: The package include a polyethylene bag inside and a paper bag outside, with a net weight of 25kg±0.25kg. BR9000 should be stored in well-ventilated, clean and dry warehouses.
