Description

Chlorosulfonated Polyethylene (CSM) is a high-performance synthetic rubber renowned for its exceptional resistance to ozone, weathering, and a wide range of chemicals, including oils and acids. This material is critical for manufacturing durable, long-lasting products that must perform reliably in harsh environmental conditions. It is essential for industries requiring robust elastomeric components, such as automotive, construction, wire & cable, and industrial fabric coating.

Application

• Industrial Hose and Belting: Used in the production of hoses and conveyor belts that handle oils, chemicals, and abrasive materials.
• Wire and Cable Insulation/Jacketing: Provides excellent weather, ozone, and flame resistance for outdoor and industrial power cables.
• Roofing Membranes and Pond Liners: Serves as a primary material for single-ply roofing systems and geomembranes due to its durability and weatherability.
• Automotive Components: Employed in seals, gaskets, and under-hood components where heat and fluid resistance are paramount.
• Coated Fabrics and Inflatable Structures: Used to coat textiles for tarpaulins, inflatable boats, and architectural structures.
• Adhesives and Sealants: Formulated into high-performance adhesives and sealants for construction and automotive assembly.
• Industrial Rollers and Linings: Provides a protective, non-corrosive lining for chemical processing equipment and rollers.

Quality Control

Our Chlorosulfonated Polyethylene is manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including chlorine content, sulfur content, Mooney viscosity, and specific gravity. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. The material is light-sensitive and should be stored away from direct sunlight to prevent degradation.
