            Chlorinated polyethylene (CPE)


            One, Introduction

            CPE is the abbreviation of chlorinated polyethylene (polyethylene chlorinated), is a high density polyethylene after chlorination of the product, the appearance of white small particles.

            Two, CPE performance

            1, excellent aging resistance, can be used in harsh climate and harsh environment, have good resistance to ozone.

            2, excellent flame retardant, no spontaneous combustion.

            3, excellent low temperature toughness, can be maintained at -20 degrees C flexibility, suitable for UPVC products, anti impact modifier.

            4, excellent resistance to chemical drugs, the majority of the performance of the chemical inert, resistant to various acid and alkali corrosion.

            5, good processing performance, easy processing molding.

            6, excellent use of safety, will not have adverse effects on the human body and the surrounding environment.

            7, excellent stability.

            Four, the main use of CPE

            CPE has the dual properties of plastics and rubber, and has good compatibility with other plastics and rubber, and therefore, in addition to a small number of used as the main material, CPE is mostly used with rubber or plastic.

            CPE and plastic is mainly as a modifier, it is mainly used as a hard polyvinyl chloride (UPVC) impact modifier UPVC products, improve the shock resistance and low temperature performance, can be used in the manufacture of UPVC doors and windows profiles, pipes and injection products etc.. With rubber, CPE is mainly to improve the flame retardant, insulation, aging resistance and so on. In addition, CPE135C can be used as a flame retardant ABS resin modifier, can also be used as an injection of PVC, PC, PE impact modifier.
