The impact of rubber reinforcement performance is mainly on tensile strength and tear strength. The general rule is that when the particle size is the same, high-structure carbon black has a large reinforcing effect on amorphous rubber, and generally has higher tensile strength. And tear strength. The structural property of rubber is also the most important factor that affects the conductive properties. The chain-like structure is apt to form interwoven conductive paths in the rubber, which will improve the conductive properties.

Butadiene rubber, whose full name is cis-1,4-polybutadiene rubber, referred to as BR, is obtained by polymerizing butadiene. Compared with other general-purpose rubbers, vulcanized butadiene rubber is particularly excellent in cold resistance, abrasion resistance and elasticity, less heat generation under dynamic load, good aging resistance, and easy to use with natural rubber, neoprene, nitrile rubber, etc.
