FAQ
Q: Where is BR9000 mainly used?
A: It is mainly used for tire tread, rubber shoe soles, conveyor belts, shock absorbers, and can also be used as a plastic modifier.
Q: What are the differences between BR9000 and styrene-butadiene rubber and nitrile rubber?
A: BR9000 has better elasticity and cold resistance, and is suitable for dynamic stress; nitrile has strong oil resistance, and styrene-butadiene has wide applicability.
Q: What are the storage precautions?
A: Store in a cool, dry, and ventilated place, avoiding direct sunlight and moisture. Do not stack more than 10 packages at a time, and the shelf life is 2 years.
