Description
Chloroprene rubber (BR), whose full name is cis-1,4-polybutadiene rubber, is a synthetic rubber with a highly regular molecular structure. Its most notable characteristics are extremely low hysteresis loss (low heat generation) and excellent abrasion resistance, making it a key material for manufacturing low-rolling-resistance tires.
Applications
Tire industry, footwear manufacturing, industrial products: hoses, sealing rings, anti-vibration rubber.
