Problems solved by technology

Chlorine-containing polymer refers to a resin containing a large amount of chlorine in its composition, which has excellent anti-corrosion properties. At present, the most widely used chlorine-containing polymer in my country is chlorinated rubber, but its application is limited by solubility, miscibility and environmental protection. However, other resins also have various characteristics of poor weather resistance and poor chemical corrosion resistance to varying degrees.
