Acid/Alkali Corrosion Resistance CPE Resin for Window/Door Profiles

Product Overview

CPE is chlorinated polyethylene polymers produced by combining chlorine and polyethylene in an aqueous slurry.Its saturated, linear high molecular structure enables CPE with many superior physical and chemical performances. As a high-performance additive, it enhances PVC applications by improving impact resistance, weather durability, and plasticizer retention in flexible films. Its adaptable properties make it ideal for cable insulation, rubber elastomers, and flame-retardant polyolefin compounds, while also serving as a reliable material for protective wire jacketing. CPE's multifunctional capabilities support diverse industrial solutions, offering manufacturers a practical balance of performance and process efficiency.

CPE is an engineered polymer derived through chlorination substitution reactions using high-density polyethylene (HDPE) as the base material. Based on molecular structure and functional applications, this versatile material is commercially categorized into two primary types:

Resin-Type CPE
Designed for thermoplastic compounding

Compatible with various resins including:
• PVC (enhanced impact/weather resistance)
• Polyolefins (PE, PP)
• Engineering plastics (PS, ABS)
• Polyurethane (PU) systems

Elastomer-Type CPE (CM)
Functions as high-performance specialty rubber

Blending capabilities with:
• EPDM (ethylene-propylene-diene monomer)
• Butyl rubber (IIR)
• Nitrile rubber (NBR)
• Chlorosulfonated polyethylene (CSM)

 

Key Technical Advantages:

Dual functionality as both standalone material and performance modifier

Customizable chlorine content (typically 34-44%) for targeted properties

Broad processing compatibility across extrusion, injection molding, and calendaring

This material's unique adaptability enables cross-industry applications ranging from weather-resistant construction profiles to chemical-resistant rubber components.
