The difference and application between CPE and ACR

CPE is the abbreviation for chlorinated polyethylene, which is the product of high-density polyethylene after chlorination, with a white small particle appearance. CPE has dual properties of plastic and rubber, and has good compatibility with other plastics and rubber. Therefore, except for a few used as main materials, CPE is mostly used in combination with rubber or plastic. When used with plastics, CPE135A is mainly used as a modifier, and its main purpose is to serve as an impact modifier for PVC products, improving the impact resistance and low-temperature performance of CPVC. Can be used for manufacturing CPVC door and window profiles, pipes, and injection molded products. When CPE is used in combination with rubber, it mainly improves the flame retardancy, insulation, and aging resistance of rubber. In addition, CPE130A is mostly used for rubber magnetic strips, magnetic sheets, etc; CPE135C can be used as a modifier for flame retardant ABS resin and as an impact modifier for PVC, PC, and PE injection molding.
ACR is widely regarded as an ideal processing aid for hard PVC products, and can be added to any hard PVC product according to different processing needs. The average molecular weight of the processed modified ACR is much higher than that of commonly used PVC resins. Its main function is to promote the melting of PVC resin, change the rheological properties of the melt, and improve the surface quality of the product. Widely used in the production of profiles, pipes, fittings, plates, corner plates, etc.
