Performance:
Compared with natural rubber and styrene-butadiene rubber, cis-butadiene rubber has the characteristics of high elasticity, good wear resistance, good cold resistance, low heat generation, good flexural resistance and dynamic performance. The main disadvantages are poor wet slip resistance, low tear strength and tensile strength, large cold flow, processing performance is slightly poor, must be used with other rubber.
Uses:
Polybutadiene rubber is mainly used in shoe making, high impact polystyrene and ABS resin modification, tire manufacturing, rubber hose, tape and other aspects.
Packaging method:
Steel bottles.
Storage and transportation conditions:
Stored in a cool, dry, well ventilated non-flammable structure of the warehouse, the best special storage. Stay away from heat and fire sources. Prevent direct sunlight.
