Chlorinated polyethylene (CPE) is a kind of
powder product which uses HDPE to suspend and chlorinate in water
phase. With the increase of chlorination degree, the original
crystalline HDPE gradually becomes an amorphous elastomer. The
content of CL in CPE used as toughening agent is generally ****5%.
CPE has a wide source and low price. Besides toughening effect, it
also has cold resistance, weather resistance, fire resistance and
chemical resistance. At present, CPE is the leading impact modifier
in China, especially in PVC pipe and profile production, most
factories use CPE. The addition amount is generally ***5. CPE can
be used in combination with other toughening agents, such as
rubber, EVA, etc., with better effect, but rubber additives are not
resistant to aging.
Â
CPE is chlorinated polyethylene, which is
made of HDPE by partial chlorination. Due to the existence of
chlorine atom, CPE has softness and some rubber properties, and
makes CPB a polar polymer with the same polar group as PVC,
increasing the compatibility with PVC, so the polymer chain can
maintain enough van der Waals force, thus improving the impact
resistance and toughening effect of PVC. Moreover, CPE has the
function of accelerating PVC melting and plasticizing. With the
increase of CPE content, the plasticizing time is shortened, the
plasticizing torque and equilibrium torque are increased, and the
viscosity of plasticized melt is increased.
