Key
Characteristics
Excellent resilience, typically blended with other polymers. |
Further
Comments
This material has a very low glass transition temperature
in the region of -75c to -100c. This results in a very low
hysterisis and good flexibility at ambient temperatures and
these properties are maintained to low temperatures. It has
high abrasion resistance in severe conditions. Mainly used
in tires in blends with natural rubber and SBR. |

Butadiene Rubber is
mixed with other rubbers to improve anti-wearing, anti- twist,
repulsive elasticity and coldness endurance.
