Introduction of CPP resin

May 07, 2021

Sunman’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

Our CPP resin has strong adhesive force on polypropylene, polyethylene, paper and aluminium coating. Therefore it is widely used in printing ink, coating and adhesive field. Its main uses are as following:
1 It is used as main resin compound printing ink production for BOPP thin film.
2 It is used as main resin for adhesive production, such as, adhesive for BOPP thin film and paper, inner coating of BOPP thin film pressure sensitive tape.

3 Because of fine film-forming property and gloss, it is used as coating in polypropylene PEPP.
