What are the differences between high chlorinated polyethylene and chlorinated rubber?
High chlorinated polyethylene (HCPE) and chlorinated rubber (CR) produced by Bontecn Group China are two widely used chlorinated polymers in the fields of anti-corrosion coatings and adhesives, but they have significant differences in chemical structure, performance characteristics, and applicabl...

Factors affecting the performance of chlorinated polyethylene (CPE):
1. Chlorine content Range and performance relationship: The chlorine content of CPE is usually 25% -45%. When the chlorine content is ≥ 35%, it has self extinguishing properties (LOI ≥ 28%), and when it exceeds 40%, the flame retardancy is significantly improved. Low temperature performance: When...

Advantages and functions of high chlorinated polyethylene HCPE
1. Core advantages Weather resistance and corrosion resistance: HCPE has a stable molecular structure, random distribution of chlorine atoms, and can resist corrosion from UV, ozone, acid, alkali, salt and other chemical media, making it suitable for harsh environments. Flame retardancy: It can s...

The reasons for the rapid development of new environmentally friendly calcium zinc stabilizers are
When producing plastic products, we use a lot of stabilizers, among which composite stabilizers are the most widely used. Even though lead salt stabilizers are inexpensive and have good thermal stability, they have been widely used. However, their lead salt powder is small, and their dust ca...

What are the differences between PVC processing aids, plasticizers, and lubricants？
Because PVC processing aids are highly compatible with PVC and have a high relative molecular weight (about (1-2) × 105-2.5 × 106g/mol) and no coating powder, they are subject to heat and mixing during the molding process. They first soften and tightly bond the surrounding resin particles. T...
