CPE135B Wire and Cable Chemical Auxiliary Agent - 36.2% Chlorine Content, 9.5 MPa Tensile Strength
CPE135B is a random, saturated thermoplastic elastomer with minimal crystalline structure, specifically formulated as a chemical auxiliary agent for wire and cable manufacturing. This advanced material features low plasticizing temperature characteristics for enhanced processing efficiency.
- Improves physical and mechanical properties when blended with EPDM rubber
- Enhances heat-resistant air aging performance and drawing permanent deformation characteristics
- Optimal performance achieved at EPDM/CPE135B blend ratio of 70/30
- Recommended dosage of 50 parts per hundred rubber (phr) for superior results
This versatile product serves as both a special synthetic rubber and modifier for general synthetic rubbers, with extensive applications including:
- Insulation layers for oil-resistant parallel flexible wires (HPN type)
- Sheaths for consumer appliance cables (heaters, cookers, air conditioners, refrigerators)
- Light, medium and heavy cable sheaths
- Mining, marine, and locomotive cable applications
- Power, instrument, and control cable insulation/jackets
- Modification of PVC profiles, pipes, magnetic materials, and ABS
