Product Overview
CPE is chlorinated polyethylene polymers produced by combining chlo rine 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.

Uses
1.Building Window & Door Profiles:
Core Function: This is the most extensive and critical application. Used in PVC window frames, sashes, and mullions.
Problem Solved: Pure PVC profiles are highly brittle and prone to cracking or breaking during installation (e.g., nailing, screwing), usage (e.g., strong wind impact, accidental collisions), or in low-temperature environments.
CPE Effect: Significantly enhances impact strength, typically achieving 300-500% or greater improvement. This ensures windows and doors withstand greater external impacts without fracturing, substantially improving product durability and safety. Concurrently, CPE's inherent weather resistance synergizes with stabilizers to resist UV radiation, high temperatures, freezing conditions, and other harsh outdoor elements, preventing re-embrittlement due to aging.
2.PVC Piping Systems:
Scope: Includes pressure pipes (cold/hot water), drain/waste/vent pipes (indoor/outdoor), sewer pipes, electrical conduits, and industrial pipes.
Problem Solved: PVC pipes face risks of impact damage, cracking, or freeze-fracturing during transportation, handling, installation (trenching, backfilling, joining), service (water hammer, external loads), and in cold climates.
CPE Effect: Addition of CPE drastically improves the impact resistance of pipes, especially at stress-concentrated points like fittings (elbows, tees, valves). It effectively absorbs impact energy, reducing breakage rates during construction and service. For buried pipes or those in cold regions, the low-temperature flexibility provided by CPE is critical, ensuring pipes remain pliable and resistant to brittle fracture even in freezing conditions.
3.PVC Sheets & Panels:
Types: Building siding/cladding, interior decorative panels, signage/display boards, furniture boards, chemical tank linings.
Problem Solved: Large-area sheets/panels are susceptible to cracking or shattering during handling, installation, or service due to bending, impact, dropping, or localized stress. Outdoor panels must also withstand wind loads and hail impact.
CPE Effect: Enhances overall toughness and impact resistance, making panels less prone to breakage. For outdoor panels, CPE's weather resistance extends service life. In chemical tank linings, impact toughness helps resist impacts from contained materials or external operations.
4.PVC Injection Molded Parts:
Products: Pipe fittings (elbows, couplings, valves, flanges), electrical switch/socket housings, distribution boxes, equipment housings/guards, tool handles, planters, storage/carrying cases.
Problem Solved: Molded parts often have complex geometries with stress concentrators like wall thickness variations, sharp corners, and ga tes. Pure PVC is highly prone to cracking at these points due to impact or internal stress. Tool handles need to withstand impact or drops.
CPE Effect: Effectively improves impact strength, specifically addressing brittleness at ga tes and cracking at sharp corners, increasing yield rates and product reliability. For parts subject to mechanical impact (e.g., guards, handles), CPE provides essential toughness.
5.Other Rigid PVC Products:
Examples:
Blinds/Curtain Tracks: Improves impact resistance during installation and use, preventing breakage.
Fencing/Railings: Enhances resistance to collisions (e.g., people or objects).
Automotive Interior Trim (non-transparent): E.g., door panel substrates, certain trim strips, improving impact resistance.
Edge Banding: Increases edge toughness, reducing chipping.
Industrial Troughs/Tanks/Ducts: Resists impacts during handling and operation.
CPE Effect: Provides a reliable cost-effective toughening solution for these rigid PVC applications requiring impact resistance.
Other Uses
In addition to the many applications described above, our products have the following features:
Chlorinated polyethylene (CPE) resin is a versatile thermoplastic elastomer renowned for its exceptional weatherability, chemical stability, and inherent flame retardancy. These superior properties have established CPE resin as a preferred material for demanding applications including wire/cable jacketing, automotive components, and waterproof roofing membranes. The material distinguishes itself through unique combination of high-impact strength and flexible endurance, positioning it as an optimal solution for engineering applications requiring robust performance under harsh environmental conditions. Notably, CPE maintains remarkable impact resistance while retaining flexibility across wide temperature ranges, making it particularly valuable for industrial products that demand both durability and structural compliance.
