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...Read more -
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...Read more -
