The difference between CPE135B and CPE 135A

Generally speaking, CPE can be divided into three categories in use, type A, type B, and type C.

Type CPE135A material is mainly used as toughening agent to modify hard pvc;

Type CPE135B material is mainly used in the rubber field, which is usually called cm;

Type CPE135C material is mainly used to modify abs. CPE is made by the substitution reaction of high-density polyethylene and chlorine gas through free radicals.

The main reason is that the molecular weight of the high-density polyethylene is different. In comparison, the high-density polyethylene used for the a-type material has a large molecular weight, and the high-density polyethylene used for the c-type material has a small molecular weight. Type CPE135A and type CPE135C generally do not require Mooney viscosity.
