IntroductionCPE is chlorinated polyethylene polymers produced by chlorination of HDPE in an aqueous slurry.The molecular chain of CPE with a certain chlorine content and low crystallinity is composed of a mixed chain segment with a high chlorine content and a low chlorine content. The compatibility

Polyvinyl chloride (PVC) is one kind of general thermoplastic with excellent properties and it is one of the most productive plastic varieties.However, PVC resin is one kind of brittle material, and continuous glass phase can not prevent the severe expansion of cracks under the action of stress, and

Lubricants are essential additives in PVC processing. Adding a proper amount of lubricant in PVC can reduce the mutual friction between the particles before the PVC melt and the macromolecules in the PVC melt; reduce the mutual friction between the PVC melt and the plastic mechanical contact surface
