Chlorinated Polypropylene (CPP)

Introductionimage.png

“SUNCHLON” is the registered trade-name of Chlorinated Polypropylene (CPP) produced by Sundow Polymers Co., Ltd.

SUNCHLON™ CPP is a thermoplastic resin produced by the chlorination of polypropylene. It is a nontoxic 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.

Application

CPP belongs to thermoplastic resins. It has strong adhesion to polypropylene (PP) as well as polyethylene, paper and aluminum film, etc. It is a high-performance adhesion promoter for paints, coating, inks and adhesives. So it is widely used in the fields of painting and adhesives and its main usages are as follows.

◆ CPP can be used as an effective binder in the manufacturing of composite ink for the films of BOPP, OPP, PET, PE, etc.

◆ CPP can be used as a composite adhesive between paper and films of BOPP, OPP, PET, PE, AL, etc., and an inner coating for pressure-sensitive adhesive tape of BOPP films.

◆ With its good film-forming and glossiness properties and its strong affinity with pigment, CPP can be used as colorant for plastic modification or as paint binder for polypropylene (PP) injection molding wares.
