Introduction of CPP resin
May 26, 2021Sunman’s CPP resin is a thermoplastic resin produced by the chlorination of polypropylene. It is a non-toxic white or light yellow granular solid and can be easily soluble in organic solvents such as chlorinated hydrocarbons, toluene, butanone or other mixed solvent. And it has high hardness and good properties of wear-resistance, acid-resistance, salt water resistance and aging- resistance.
Chlorinated polypropylene is produced by means of trichloromethane solvent method in the production process, which dissolves polypropylene in the solvent, and then passes into chlorine gas for chlorination reaction. After the chlorinated solution is removed, the chlorinated polypropylene solution is obtained, and the chlorinated polypropylene solution is dried and granulated to obtain chlorinated polypropylene products.
3 Because of fine film-forming property and gloss, it is used as coating in polypropylene PEPP.
