Product Description

Product Description

CPE Resin

Chlori nated Polyethylene (CPE) is a versatile thermoplastic polymer obtained by the chlorination of high-density polyethylene (HDPE). It exhibits a unique combination of flexibility, chemical resistance, and weatherability, making it suitable for a wide range of industrial applications. CPE is available in various grades, differentiated by chlo rine content, density, melt flow index, and particle size. The polymer is often supplied as fine powder or granular form for ease of processing.

Key properties of CPE include:
- Excellent impact resistance even at low temperatures
- Good flexibility and elongation
- Resistance to UV radiation, ozone, and weathering
- Chemical and oil resistance
- Compatibility with PVC, rubber, and other thermoplastics

Application

 

PVC Modification
CPE is commonly used to modify PVC to improve impact resistance, flexibility, and low-temperature performance. This is particularly valuable in producing rigid and semi-rigid PVC products like pipes, profiles, window frames, and siding.

Wire and Cable Insulation
CPE's excellent electrical insulation properties, combined with flexibility and resistance to weathering, make it ideal for use in power cables, control cables, and flexible cords. It enhances low-temperature flexibility and mechanical durability.

Automotive Applications
In automotive industries, CPE is used in weatherstrips, seals, bumpers, gaskets, and hoses. It provides excellent resistance to oils, fuels, and aging, while maintaining elasticity over time.

Waterproofing Membranes
CPE is widely employed in roofing membranes, waterproofing sheets, and geomembranes due to its water resistance, UV stability, and long-term durability. It maintains flexibility under extreme temperature variations.

 Flooring and Synthetic Leather
CPE is added to vinyl flooring, artificial leather, and coated fabrics to enhance flexibility, impact strength, and wear resistance.

CPE can be blended with natural rubber, SBR, or EPDM to improve impact resistance, weatherability, and low-temperature performance. This is widely used in hoses, belts, and gaskets.

FAQ

Q1: Can CPE be used in outdoor applications?
A1: Yes, CPE exhibits excellent resistance to UV radiation, ozone, and weathering, making it suitable for outdoor use in roofing membranes, seals, and cable jacketing.

Q2: What is the difference between CPE and EPR/EPDM rubber?
A2: CPE is a chlorinated polyethylene thermoplastic, providing better processability and chemical resistance, while EPDM is an elastomer with superior elasticity and heat resistance. CPE is often used as a modifier or blend to improve specific properties of other polymers.

Q3: How does CPE affect the impact resistance of PVC products?
A3: Adding CPE to rigid or semi-rigid PVC improves toughness, low-temperature flexibility, and impact strength. Typical formulations use 5–15% CPE depending on the desired property enhancement.
