Product Description

Products: Chlorinated Polyethylene (CPE) 

Overview

Chlorinated polyethylene (CPE) is a high-performance thermoplastic elastomer widely used as a key modifier in the plastics manufacturing process. Through controlled chlorination of polyethylene, CPE combines excellent flexibility, chemical resistance and durability. Its unique molecular structure is compatible with polyvinyl chloride (PVC), making it an ideal additive for enhancing the mechanical and environmental stability of plastic profiles.CPE has been specifically engineered to meet the stringent requirements of modern building materials, ensuring long term performance in a wide range of climatic conditions.

Chemical Structure & Versatility
CPE is a chemically modified polymer created by chlorinating high-density polyethylene (HDPE). The chlorine content (typically 34-44%) is uniformly distributed along the polymer chain, forming a saturated elastomer with a mix of amorphous and crystalline regions. This structure enables:

Compatibility: Seamless blending with PVC, rubber, and other polymers.
Tunability: Adjusting chlorine content and molecular weight to tailor properties like flexibility, hardness, or flame retardancy.

Key Advantages of CPE

Superior Low-Temperature Resistance
CPE retains flexibility and impact strength even at extreme temperatures as low as -35°C. This property prevents cracking or brittleness in plastic door and window profiles during harsh winters, ensuring structural integrity in cold climates.

Enhanced Thermal Stability
With a thermal decomposition temperature exceeding 170°C, CPE improves the heat resistance of PVC blends. This stability minimizes deformation and maintains dimensional accuracy in high-temperature environments, such as sun-exposed façades.

Outstanding Weather Resistance
The chlorination process imparts excellent resistance to UV radiation, ozone, and oxidative degradation. CPE-modified profiles resist fading, chalking, and embrittlement, extending the lifespan of plastic doors and windows in outdoor applications.

Optimized Processing Performance
CPE enhances the melt flow and compatibility of PVC blends, allowing for smoother extrusion and molding processes. This results in uniform profiles with reduced defects, lowering production costs and improving efficiency.

Eco-Friendly Formulation
Modern CPE grades are formulated with sustainable additives, such as halogen-free flame retardants, aligning with green building standards and reducing environmental impact.

Applications in Plastic Doors and Windows

1. Profile Reinforcement
   CPE is blended with PVC to create durable window and door frames that withstand mechanical stress, temperature fluctuations, and weather exposure. Its flexibility ensures tight sealing and smooth operation of moving parts.

2. Sealing Components
   CPE-based gaskets and seals provide superior elasticity and weather resistance, preventing air and water infiltration in energy-efficient buildings.

3. Impact-Resistant Accessories
   Hardware components, such as corner connectors and hinge supports, benefit from CPE's shock-absorbing properties, reducing wear and tear over time.

4. Adaptability to Diverse Climates
   From arid deserts to coastal regions, CPE-modified profiles maintain performance in humid, salty, or polluted environments, making them suitable for global construction projects.

   

   

    

 

1. Low-Temperature Resistant CPE
Weifang Phoenix's flexible-chain structured CPE is engineered with advanced molecular design to maintain ductility at -35°C, ensuring plastic door and window profiles resist cracking in Arctic climates. This innovation powers their Nordic-certified window systems, which pass EN 14351-1 impact tests at -40°C.

2. Thermally Stable CPE
The company's high-heat-resistant CPE incorporates proprietary stabilizers and PVC blending technology, enabling profiles to withstand 170°C+ processing temperatures without deformation. This thermal stability underpins their Middle East-focused product lines, validated by ASTM D635 fire-resistance standards in Dubai's extreme heat.

3. Processing-Optimized CPE
The company's high-flow CPE/PVC blends reduce extrusion energy consumption by 15-20%, enabling mass production of precision profiles. Their patented nano-modified CPE (with metal oxide fillers) further enhances flame retardancy and UV resistance, now deployed in industrial-scale manufacturing.
