CPE-135B Impact Modifier for Soft PVC and Rubber Products | China Suppliers and Factory

CPE-135B is a premium thermoplastic elastomer primarily utilized in the manufacturing of rubber and PVC products. Sourced from top China suppliers and produced in advanced factories, CPE-135B is derived from chlorinated high-density polyethylene, ensuring outstanding elongation at break and superior toughness. This saturated thermoplastic resin features an irregular structure that significantly enhances its performance. When blended with PVC and rubber, CPE-135B exhibits excellent extrusion flow, making it an ideal choice for various applications. Experience the quality and reliability of CPE-135B, your go-to solution for high-performance materials

    Products Description

    It is a general term for 35% chlorine content rubber type CM, which is mainly used in the rubber field. Its processing performance is also very good, and it can produce rubber products with smooth, round and flowing matte surface. It can replace a variety of rubber in various fields and produce rubber products with excellent performance.

    CPE-135B contains almost no crystals, and has excellent flame retardancy, electrical insulation, chemical resistance, oil resistance and water resistance; it has good compatibility with PVC, Cr, NBR, etc., and can be used as ABS products flame retardants, wire and electrical enclosures, flexible PVC foams, specialty synthetic rubbers, modifiers for general-purpose synthetic rubbers, and plasticizers for PVC and other plastics. Compared with the common chlorinated polyethylene on the market, Bontecn chlorinated polyethylene has the characteristics of low glass transition temperature, superior processing performance and high elongation at break. It is a high-performance, high-quality specialty rubber. It can be used alone or in combination with ethylene-propylene rubber, butadiene-propylene rubber and chlorostyrene rubber to produce rubber products. The products produced have a long service life and are UV resistant. No matter how harsh the environment and climate, they can maintain the inherent properties of rubber for a long time.
