Chloroprene
Resonac Chloroprene
About the product
Chloroprene Rubber is a synthetic rubber produced by the emulsion polymerization of chloroprene. It offers an excellent balance of mechanical strength, weather resistance, chemical resistance, and heat resistance. We provide both dry grades and latex grades, with a comprehensive product lineup optimized for a wide range of applications through careful control of crystallization rate and gel content.
