Product Description

Product Introduction

Chlorosulfonated polyethylene rubber (CSM) is a specialty rubber made from polyethylene through chlorination and chlorosulfonation. Its molecular chain is fully saturated, and its side groups contain -CL and -SO2CL. It can be vulcanized with a variety of vulcanization systems. It exhibits excellent colorability, weather resistance, ozone resistance, heat resistance, and chemical resistance.

FAQ

Q1: Is CSM suitable for high-temperature or fire-resistant applications?
A: CSM typically withstands continuous temperatures up to 130°C (short term: 150°C). It is not inherently flame-retardant, but flame retardancy can be achieved through the use of compatible additive systems.

 
Q2: Can customers select different viscosity (Mooney) grades for specific applications?
A: Absolutely. We offer CSM grades ranging from low to high Mooney viscosity (30–120), allowing you to choose the ideal flow and mechanical profile for coatings, adhesives, soft hoses, and molded goods.

 
Q3: Are samples and technical support available?
A: Yes. We provide free sample quantities and formulation consultation, including curing systems, filler compatibility, and processing guidelines.
