Applications and characteristics of chlorinated polyproylene

Chlorinated polypropylene (CPP) has a wide range of applications in various fields, primarily including coatings, inks, and adhesives.

Coatings Industry

Chlorinated polypropylene plays a vital role in the coatings industry, often used in manufacturing high-performance anticorrosion and decorative coatings. Due to its excellent weather resistance, chemical corrosion resistance, and adhesion, chlorinated polypropylene is widely used in construction, automotive, and shipbuilding industries. In addition, chlorinated polypropylene can also be used as a release agent for polypropylene injection molding and as a coating for BOPP film.

Ink Industry

In ink production, chlorinated polypropylene serves as a key raw material, enhancing the printing performance, wear resistance, and water resistance of inks. Inks containing chlorinated polypropylene produce more vibrant colors and higher clarity during printing, making them highly favored in the printing industry. It is a primary component in the production of BOPP film composite inks.

Adhesives Industry

Chlorinated polypropylene also has important applications in adhesive production, enabling the creation of adhesives with strong bonding strength, water resistance, oil resistance, and high-temperature resistance. These adhesives are widely used in packaging, footwear, and furniture manufacturing industries. Additionally, chlorinated polypropylene can be used as an adhesive for BOPP film and paper, as well as a primary raw material in other adhesive production.

The application characteristics of chlorinated polypropylene (CPP) mainly include its excellent bonding properties, physicochemical properties, and wide range of applications.

Chlorinated polypropylene is a thermoplastic resin obtained by chlorination modification of polypropylene. Its appearance is a white amorphous solid, white or light yellow powder, or yellow or light yellow granules. It is non-toxic and soluble in halogenated hydrocarbons, toluene, and other solvents. Depending on the chlorine content, its melting point is generally between 80-160℃, and its decomposition temperature is between 70-200℃. Low chlorine content products begin to decompose slowly above 40℃, and the decomposition rate is extremely fast above 70℃.

Bonding Properties

Chlorinated polypropylene exhibits excellent bonding properties to polypropylene surfaces and good bonding properties to various materials such as polyethylene, paper, and lead film. This makes it widely used in the ink, coating, and adhesive industries.
Physicochemical Properties
Chlorinated polypropylene possesses good hardness, wear resistance, salt water resistance, and aging resistance. These characteristics allow it to maintain stable performance in various environments, making it suitable for various industrial applications.
Application Areas
Inks and Coatings: Chlorinated polypropylene is used as a primary raw material in printing inks, especially in printing inks for composite materials such as double-layer PP film, PP film-paper, and PP film-aluminum. It is also used as a color carrier and waterproofing agent in coatings.

Adhesives: Due to its excellent bonding properties, chlorinated polypropylene is widely used in plastic and metal adhesives, particularly in the packaging industry for producing adhesives for composite materials such as double-layer PP film, PP film-paper, and PP film-aluminum.
Flame Retardants: Due to the chlorine atoms in its molecular chain, chlorinated polypropylene also has some applications in flame retardants.
Other Applications: It also has wide applications in automotive plastic substrate primers (such as bumpers, interior parts, wheel housings, etc.), film ink adhesives, plastic molding containers and food packaging film adhesives, construction, paints and coatings primers, etc.
