Description

Ethene, Chloro-, Polymer With Ethene CAS NO 25037-78-9 is a high-performance chlorinated polyethylene (CPE) copolymer, valued for its excellent balance of flexibility, chemical resistance, and weatherability. This material is a critical additive and modifier, enhancing the physical properties of base polymers for demanding industrial applications. It is primarily sought by manufacturers in the plastics, wire & cable, and automotive industries for producing durable, flame-retardant, and impact-resistant compounds.

Application

• Polymer Modification: Acts as an impact modifier and compatibilizer for polyvinyl chloride (PVC), polyolefins, and engineering plastics.
• Wire and Cable Insulation/Jacketing: Imparts flexibility, flame retardancy, and excellent resistance to oils and chemicals in cable compounds.
• Automotive Components: Used in under-the-hood applications, seals, hoses, and profiles requiring heat and oil resistance.
• Roofing Membranes and Geomembranes: Provides long-term durability, weather resistance, and flexibility in single-ply roofing systems.
• Hose and Tubing: Enhances the chemical resistance and flexibility of industrial and automotive hoses.
• Adhesives and Sealants: Serves as a base polymer or additive to improve adhesion and elasticity.
• Magnetic Stripe Coatings: Used as a flexible, durable binder in the production of magnetic media.
