Product Overview
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.

Core Application Scenarios of CPE in Magnetic Materials
1. Household Magnetic Products
Refrigerator Magnets/Message Board Clips
Role: Serves as a flexible carrier, enabling magnets to bend and conform to curved refrigerator surfaces while allowing easy surface printing (superior to rigid PVC magnets).
Magnetic Puzzle Toys
Role: Provides impact-resistant flexibility, preventing shattering when chewed by children (replaces aging-prone rubber magnets).
2. Industrial Magnetic Components
Flexible Magnetic Seals (refrigerator doors, purification equipment)
Role: Ensures airtight adhesion between seals and metal frames through flexibility (solves rubber magnetic strips' cold-weather hardening issues).
Magnetic Access Panels for Equipment Maintenance
Role: Enables quick installation/removal; CPE's oil resistance prevents swelling failure upon contact with machinery oil (conventional magnets deform easily)
3. Office & Educational Supplies
Whiteboard Magnetic Clips
Role: Holds documents while adhering to whiteboards; CPE's high elasticity prevents breakage from repeated use (replaces brittle PS plastic).
Teaching Demonstration Magnets
Role: Lightweight design (30% lighter than rubber magnets), facilitating student handling.
4. Innovative Functional Materials
Automotive Anti-Slip Pads with Magnets (dashboard mounts for phone holders)
Role: Magnetic base for fixation + CPE anti-slip surface texture, preventing displacement during vehicle vibration.
Custom-Cut Magnetic Wall Decals
Role: User-trimmable shapes; CPE's tear resistance prevents edge cracking during cutting.
Other Uses
In addition to the many applications described above, our products have the following features:
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.
