Chlorinated Polyethylene CPE Material for Enhancing Cold Resistance in Outdoor Plastic Applications¹

Preview:

Product Description Product OverviewCPE is chlorinated polyethylene polymers produced by combining chl0rine 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.

As an impact modifier, CPE is widely used to toughen plastics like PVC and ABS due to its exceptional flexibility, weather resistance, and compatibility, significantly enhancing the impact strength of materials.1. Toughening PVC Rigid Products (Primary Use)Window/Door Profiles: Adding 8-12% CPE improves impact resistance (falling dart impact strength ≥15 kJ/m2), replacing traditional ACR/MBS modifiers.Pipes & Sheets: Used in UPVC drainage pipes and construction templates, enhancing low-temperature impact performance (>90% pass rate at -10°C).2. Automotive & TransportationDashboards, Bumpers: Blended with ABS/PP to improve weather resistance and gravel impact resistance.EV Battery Housings: Flame-retardant CPE (chl0rine content ≥40%) + ATH synergists meet UL94 V-0 standards.3. Wire & CableInsulation Sheaths: CPE-modified PVC sheaths resist oil and cracking, ideal for outdoor cables (e.g., photovoltaic cables).4. Other FieldsPackaging: Transparent CPE (low chl0rine content) for food packaging films, balancing toughness and clarity.Footwear: Soft CPE (with DOP) replaces rubber to reduce costs. Usage Guidelines1.Dosage:Rigid PVC: 5-15% (adjust based on impact requirements).Flexible products: 10-20% (use with plasticizers).2.Processing:Dry-blend with PVC resin before extrusion/injection (no pre-activation needed).Processing temperature: 160-190°C (avoid >200°C to prevent decomposition).3.Formulation Tips:Add stabilizers (Ca/Zn or lead-based) to prevent HCl release during processing.For transparent products, blend with MBS (e.g., CPE 240S + 5% MBS).Market Trends:1.Eco-Friendly: Halogen-free flame-retardant CPE (e.g., phosphorus-nitrogen systems) for RoHS/REACH compliance.2.High Performance: Nano-SiO2/carbon nanotube-reinforced CPE for EV battery components.3.Recycled CPE: Chlorinated recycled PE to reduce carbon footprint (e.g., Sabic's PCR-CPE).
