The characteristics and industrial applications of HCPE (High Chlorinated Polyethylene

High chlorinated polyethylene (HCPE) is a thermoplastic resin obtained through deep chlorination modification of polyethylene, and its chlorine content usually reaches 60% to 70%. This special structure endows it with excellent chemical stability, flame retardancy and weather resistance, mainly presenting three core characteristics:

1. Anti-corrosion performance: The high-density chlorine atoms in the molecule form a shielding layer, which can resist the erosion of acids, alkalis, salts and organic solvents.

2. Physical properties: While retaining the flexibility of polyethylene, the glass transition temperature is raised to over 120℃.

3. Processing Advantages: It has good compatibility with materials such as alkyd resin and epoxy resin.

In the industrial field, HCPE is mainly used in heavy-duty anti-corrosion coatings (accounting for 75% of global consumption), cable sheaths and building waterproofing membranes. China's HCPE production capacity has exceeded 200,000 tons per year in 2024, with Shandong and Jiangsu being the main production bases. The current technological research and development focuses on optimizing the low-temperature chlorination process to reduce production energy consumption and minimize the emission of by-products.

The HCPE products produced by AXA feature outstanding performance: 65% chlorine content, excellent weather resistance, flame retardancy and chemical stability. The special modification process endows the product with both rubber elasticity and plastic strength, making it perform exceptionally well in the fields of anti-corrosion coatings and waterproof membranes. It has good compatibility with various resins and can significantly improve the performance of composite materials. The company is equipped with a professional technical service team to provide customers with continuous solutions.
