High Chlorinated Polyethylene (HCPE) Resin for Adhesives, Paints, and Coatings - China Suppliers & Factory

HCPE, or high chlorinated polyethylene, is a premium-grade resin produced by leading manufacturers in China. With a relative density of 1.35-1.45 and an apparent density ranging from 0.4-0.5, this material boasts a chlorine content exceeding 65%. HCPE exhibits excellent thermal stability, with a decomposition temperature above 130°C and a stability time exceeding 3mm at 180°C, making it an ideal choice for various applications. As trusted suppliers of HCPE resin, our factory ensures high-quality production and reliable performance.

Product Details

Products Description

White light small particles. Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance and oil resistance. Used to replace chlorinated rubber in adhesive production.

Important Processing Note: HCPE can also be used as adhesives, paints, flame retardants, and high-grade ink modifiers, which can improve adhesion, corrosion resistance, flame retardancy, and abrasion resistance. Used as paint raw material, the main anti-corrosion effect is chloride ion, so when grinding in summer, when the grinding temperature exceeds 60°C, it is necessary to consider cooling or separately configure the solution to add to the finished tank, because at 56°C, chloride ion precipitates. The anti-corrosion performance of paint is reduced, and heavy anti-corrosion paint is applied.

HCPE-A has a high molecular weight and high viscosity, resulting in extremely strong adhesive properties. It dissolves stably in organic solvents such as toluene and xylene, forming colorless or pale yellow transparent solutions. Its key characteristics are its low molecular weight and relatively low viscosity, yet its high bonding strength. It can be used in adhesives produced for a variety of PVC pipes, fittings, sheets, and other materials. It is typically packaged in 20kg bags.

Application Fields

Used instead of chlorinated rubber to make adhesives. It can also be used as a modifier for adhesives, high-grade inks and other products, which can improve adhesion, corrosion resistance, flame retardancy, and wear-resistant parts.

Storage Recommendation: Store in a cool, ventilated and dry warehouse, away from moisture.

HCPE-A

A resin designed for high-performance adhesives, particularly excelling in bonding PVC materials. It can bond various pipes, fittings, and sheets made of polyvinyl chloride (PVC) or chlorinated polyethylene (CPE), as well as metals. It can also be used in the fiber industry. If your work requires strong bonding, HCPE-A is an excellent choice.

HCPE-H (High Viscosity)

Mainly used for anti-corrosion coatings and fire-resistant coatings as a substitute resin for chlorosulfonated polyethylene.

HCPE-M (Medium Viscosity)

Can be used as a special resin for steel anti-corrosion coatings and surface coatings for buried pipelines.

HCPE-L (Low Viscosity)

Due to its low viscosity, it can be compatible with acrylic resin and alkyd resin, and can be used as a special resin for anti-corrosion coatings, container coatings, road marking paints, and surface coatings for buried pipelines.

Due to the regular molecular structure, saturation, low polarity and good chemical stability of chlorinated rubber, various anti-corrosion coatings prepared with it have the characteristics of fast drying of coating film, good adhesion, resistance to chemical media and excellent resistance to moisture penetration.

Highly chlorinated polyethylene HCPE has excellent atmospheric aging resistance and chemical medium resistance, is easily soluble in aromatic hydrocarbons, esters, ketones and other organic solvents, and has good compatibility with most inorganic and organic pigments used in coatings. Generally, it is suitable for dissolving into 40% solid content resin solution for painting.

Frequently Asked Questions

What are the main performance advantages of HCPE?

HCPE features good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance, and oil resistance. This is because its molecular structure does not contain double bonds and the chlorine atoms are randomly distributed.

What precautions should be taken when grinding HCPE paint in summer?

When the grinding temperature exceeds 60°C, cooling must be considered, or the solution must be configured separately to add to the finished tank. This is because chloride ions precipitate at 56°C, which reduces the anti-corrosion performance of the paint.

What are the typical applications of HCPE-A?

HCPE-A is primarily designed for high-performance adhesives, particularly for bonding PVC pipes, fittings, sheets, and metals. It is also used in the fiber industry.

How do HCPE-H, HCPE-M, and HCPE-L differ in application?

HCPE-H (high viscosity) is used for anti-corrosion and fire-resistant coatings. HCPE-M (medium viscosity) is ideal for steel anti-corrosion and buried pipeline coatings. HCPE-L (low viscosity) is compatible with acrylic/alkyd resins, suitable for container, road marking, and pipeline coatings.

How should HCPE be stored?

HCPE should be stored in a cool, ventilated, and dry warehouse, keeping it well away from moisture to preserve its properties.

What solvents are suitable for dissolving HCPE?

HCPE is easily soluble in aromatic hydrocarbons, esters, ketones, and other organic solvents. Generally, it is suitable for dissolving into a 40% solid content resin solution for painting applications.
