Chlorinated Polypropylene (CPP) is a thermoplastic resin .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.
CPP-C (non-toluene solution type) is easily soluble in various organic solvents and has a good compatibility with various kind resins. So you can select from the wide range of solvents to prepare solution, and good to use in various ink systems such as gravure and flexo inks.
Appearance: pale-yellow granules solid
Odor: Resin itself
Free chlorine: None
Flammability: None flammable
Good solvents: Methyl cyclohexane(MCH)，ethyl acetate，Propyl ethanoate，butyl acetate, NPAC

(1)Viscosity value is measured in 20% toluene solution at 25°C by a rotary viscometer with speed of 750 r/min.
(2) Upon the request of the customers, chlorine content and viscosity can be controlled in a range of 1% and ±50 mPa.s, respectively.
(1 ) CPP-C (non-toluene solution type) is easily soluble in various organic solvents and has a good compatibility with various kind resins. So you can select from the wide range of solvents to prepare solution, and good to use in various ink systems such as gravure and flexo inks.
(2) CPP can be used as an effective binder in the manufacturing of composite ink for the films of BOPP, OPP, PET, PE, etc.
(3) 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.
(4) 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.
The service performance of CPP is relative to the indexes of chlorinating degree and viscosity, etc. So the CPP with different indexes has varieties of usages and should be used under the specialized engineer’s instruction.
The common method is: Dissolve the product into the toluene or other solvents to prepare a solution of 20~30%. Then add the solution into the ink or other relevant products based on the ink formulation.
