How to detect the authenticity of chlorinated polyethylene

Chlorinated polyethylene (CPE) is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier for PVC plastics, and also a synthetic rubber with good comprehensive properties. It has a wide range of applications, but we can't distinguish the authenticity of the product. We will explain it in this respect below.

[let's explain the testing method of chlorinated polyethylene (CPE) for you]

1. Prepare two cans, put two kinds of chlorinated polyethylene, put the cans on the alcohol lamp to bake, the first dissolved is fake.

2. After dissolution, the tensile force is strong and the toughness is good, which is true.

3. Use purple light to irradiate, there is fluorescent agent in chlorinated polyethylene, that is fake.

Chlorinated polyethylene (CPE) can also be blended with polypropylene, high and low pressure polyethylene, ABS, etc., to improve the flame retardancy, aging resistance and printing performance of these plastics. CPE can be regarded as a random copolymer of ethylene, polyethylene and 1.2-dichloroethylene. Its molecular chain is saturated and polar chlorine atoms are randomly distributed, so it has excellent physical and chemical properties.
