Chlorinated Polypropylene

CK-300

1. Brief Introduction

Chlorinated Polypropylene (CPP), CK-300 is a thermoplastic resin manufactured from polypropylene (PP) through chemical modification.
 

2. Main Physical-Chemical Properties

CPP is a nontoxic light yellow granular solid. Depending on the difference of chlorine content, its melting point is generally in the range of 80~160 ℃ and its decomposition temperature 120~200℃. It is easily soluble in some organic solvents like halogenated hydrocarbons, toluene, acetic ether, butanone, ester, etc. and it has high rigidity and good properties of wear-resistance, acid-proof, salt water-tolerance and aging-preventing.

3. Main Specifications

Chlorinated Content:  29—33%

Viscosity:         200—400 mpas·s

Ph:               5.5—7.0

4. Main Applications

CPP belongs to thermoplastic resins. It has strong adhesion to polypropylene (PP) as well as polyethylene, paper and aluminum film, etc. So it is widely used in the fields of ink, painting and adhesives and its main usages are as follows：

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

(2) 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.

(3) 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.

5. Packing, Storage and Transportation

(1) The product is packed into a fiberboard box lined with an internal polyethylene bag.

Net weight of each piece is 20 kg.

(2) It should be stored in a dry and ventilated place. In general case, it should not be stored and transported together with other products.
