    1. Chlorinated polypropylene


      • Description of the product

      Chlorinated polypropylene is a thermoplastic resin prepared through the chlorination of polypropylene. It appears as a white solid in random powder, white or light yellow in color. It is non-toxic, dissoluble in solvents such as halogenated hydrocarbon and toluene, with a melting point ranging generally between 80-160℃, and its decomposition temperature 70-160℃, varying according to the differences in the chlorine contents. Low-chlorine content product starts to decompose slowly at a temperature above 40℃, and can decomposes very quickly when the temperature is above 70℃. Chlorinated polypropylene is widely used in the industries dealing with coatings, particularly composite inks.

      • Product name

      Product name: Chlorinated polypropylene (CPP)

      • Product application

      Apart from good adhesion to polypropylene, polyethylene, paper, lead film and other materials, the product also has resistance to abrasion, salt water aging. Therefore, it is widely used in industries involving printing inks, plastic and metal binder, especially for the production of printing ink used for double-layer PP film, PP film-paper, PP film-aluminum and other composite materials in packaging. In addition, it is applicable in paint colorants and waterproofing agents.
