CPE-135A


Chemical name: chlorinated polyethylene.CPE-135A is chlorinated polyethylene, which is produced by chlorination of HDPE, which is used to replace the hydrogen atoms on HDPE molecular chains. 


Three key factors that affect CPE performance:

1. The kinds of PE -- The CPE obtained by high molecular weight polyethylene with high viscosity and tensile strength, but the adhesion between the CPE and PVC resin is low. With low molecular weight polyethylene CPE of viscosity and tensile strength is low, the income of high density polyethylene CPE has good heat resistance performance.


2. The size of the raw material particles -- the particle size is too small to form the gelatine or lump CPE, the distribution of chlorine is not uniform when the particle size is too large, it is difficult to dissolve in the organic solvent, and the particle size range is the best in 0.1-200.


3.The level of CPE chlorination. If it is less than 25%, which is incompatible with PVC and cannot be used as modifier. The chlorine content is greater than 40%, and it has good compatibility with PVC, which can be used as a solid plasticizer and is not suitable for impact modifier.CPE with chlorine content of 36-38% has good elasticity and compatibility with PVC, so it is widely used as anti-impact modifier for PVC.Now use up to 35% of CPE is chlorine, chlorine content in about 35% of the CPE its crystallinity and glass transition temperature are low, has the good rubber elasticity, and the compatibility with PVC is appropriate, widely impact modifier for rigid PVC products.
