Brief Introduction of CPE 135A

Summary

CPE 135A is a high molecular copolymer made from HDPE and chlorine with linear molecular structure, it’s a kind of thermoplastic elastomer. it has a series of excellent performance, like: heatproof, weather-proof, flame-retardancy, chemical-resistance and ozone-resistance, its basic function is to improve the weatherability and impact strength of PVC finished products.

CPE 135A is a high molecular copolymer made from HDPE and chlorine with linear molecular structure, it’s a kind of thermoplastic elastomer. it has a series of excellent performance,  like:  heatproof, weather-proof, flame-retardancy, chemical-resistance and ozone-resistance, its basic function is to improve the weatherability and impact strength of PVC finished products.

CPE 135A developed by our company owns with excellent elongation rate at break and lower hardness,displaying outstanding toughness therefore it can largely increase the impact strength and ductility of PVC finished products.
