Q:The silica gel of the kettle is the white one that is waterproof and leaked out

Polybutadiene rubber (BR) is a cis structure by polymerization of butadiene rubber. The utility model has the advantages of good elasticity and wear resistance, good aging resistance, excellent low-temperature resistance, small heat generation under dynamic load and easy metal bonding. The disadvantage is low strength, poor tearing resistance, poor processability and self adhesion. Temperature range: about 60 + 100 DEG C. Usually used in combination with natural rubber or styrene butadiene rubber. It mainly produces tyres, tread, conveyor belts and special cold resistant products.
