Product Details : 

Co-extruded wood-plastic, also known as second-generation wood-plastic composite (WPC), represents an innovative upgrade based on traditional WPC materials. This technology integrates a wood-plastic substrate with a high-toughness plastic protective layer (typically PE or ASA) through one-step heating, molding, and pressing, eliminating the use of adhesives throughout the production process to avoid chemical pollution. The "substrate+protective layer" dual-structure design completely eliminates gaps between layers, enhancing overall product strength and delivering durability and protective performance unattainable by traditional WPC.

Core Technical Features

1. Adhesive-Free Eco-Friendly Process
   By replacing traditional gluing with physical co-extrusion, this technology achieves material bonding without formaldehyde emission, meeting green building material standards.
2. Dual-Structure Innovation
   • Substrate Layer: Composed of wood fibers and plastic (mainly PE), it retains the natural texture of wood and the water resistance/insect resistance of plastic.
   • Protective Layer: A surface co-extruded PE or ASA layer (with ASA offering superior UV resistance) forms a high-toughness shield, significantly enhancing wear resistance, scratch resistance, and stain resistance.
3. ASA Material Upgrade (Key Breakthrough of 2nd Generation)
   Compared with ordinary PE co-extrusion layers, the ASA (acrylic copolymer) protective layer provides stronger weather resistance, resisting long-term UV erosion and delaying fading/brittleness. This makes it ideal for high-light or harsh-climate environments.
