High Chlorinated Polyethylene Resin (HCPE) - Durable Solution from China Suppliers and Factory

High chlorinated polyethylene resin (HCPE) is a premium product manufactured in China through an advanced chlorination process that transforms polyethylene into a highly stable chlorinated polymer. This resin contains 65-69% chlorine and is characterized by its transparent, hard, and brittle thermoplastic properties. Renowned for its exceptional chemical stability, HCPE offers outstanding resistance to saltwater and ultraviolet (UV) exposure. Easily soluble in polar organic solvents like toluene, xylene, and esters, it forms a colorless to pale yellow, transparent solution. Notably, HCPE is free from double bonds in its molecular structure, with chlorine atoms randomly distributed throughout. When applied to surfaces such as metal, concrete, or paper, the solvent evaporates at room temperature, leaving behind a transparent, hard, glass-like film. This film provides excellent moisture and oxygen barrier properties while demonstrating high resistance to a variety of chemicals, including acids and alkalis. As a result, this product not only protects substrates from corrosion but also serves as a decorative top coating. As a leading supplier and factory of high chlorinated polyethylene resin in China, we ensure superior quality and reliability for all your application needs.

    PRODUCT INTRODUCTION

    HCPE resin can be used as gravure printing ink, the binder of heavy-duty anticorrosion paint, waterproof paint and the component of adhesives. Particularly, due to its high corrosive resistance to Cl-, it is especially suitable for being used on vessels, docks, containers coating. The paint made of HCPE can be used in chemical equipment, oil field pipelines, offshore facilities, ship coatings, metallurgy and mine, salt industry, fishing ground, wastes treatment, transportation facilities, container and electrical equipment.

    HCPE has good film forming property, weather resistance, ozone resistance, heat aging resistance, flame retardant, chemical corrosion resistance. It is mainly used for anti-corrosive coatings, fireproof coatings, adhesives and other fields.

    HCPE-101L (Low viscosity) and HCPE-201M (Medium viscosity) are mainly used for anti-corrosive coatings, such as container coating, buried pipeline coating, steel structure anti-corrosive coating and fire retardant coating, road marking paint, etc.

    HCPE-301H (High viscosity) is used for the production of PVC/CPVC adhesive. Such as for hard pipe, pipe fitting, socket, ABS, organic glass and other thermoplastics.
