Introduction:
CPE, short for chlorinated polyethylene, is a material obtained through the substitution of hydrogen atoms with chlorine atoms in HDPE, which exists as a white powder, non-toxic and tasteless.
The commonly used grade of CPE is CPE-135A in PVC rigid products as impact modifier. The impact modification effect of CPE is to form a physical cross-linked network in PVC compound, and enclose the primary particles formed by the rupture of PVC in the network formed by CPE elastomer. At the same time, there are diffusion molecular chains between PVC primary particles and secondary particles to improve the impact strength of the CPE/PVC blend system.
CPE also has outstanding weather resistance, good abrasion resistance, heat resistance, low temperature performance and chemical resistance properties apart from excellent impact strength.
