CPE-135B/888 Impact Modifier for Soft PVC and Rubber Products | China Suppliers and Factory
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.
