Co-extrusion WPC decking refers to wood-plastic composite material as the core material, and modified polyethylene PE or other polymers as the surface layer materials, co-extruded wood plastic profile products.
Simply put, it refers to a solid board prepared by extrusion after mixing plastic, wood fiber powder, and additives in a certain proportion. The surface of co-extrusion WPC decking has a uniform and strong coating co-extrusion layer, so the second-generation co-extrusion WPC decking has the characteristics of mildew-proof, insect-proof, wear-resistant, scratch-resistant, stain-resistant, weather-resistant, etc. It is especially suitable for outdoor use in places with high traffic flow.
Compared with traditional wood-plastic composite materials, co-extrusion WPC decking improves the overall performance of the material through surface coating and greatly extends its service life. In particular, adding light stabilizers, flame retardants, etc. to the surface layer provides a more functional flooring product. The protective layer, which is mainly made of functional polymer materials on the surface, has stronger resistance to oil stains and dust adhesion. Oil stains and water stains such as drinks will not penetrate into the interior of the floor. Its unique coating technology makes the floor surface feel delicate and soft, have low thermal conductivity, and be anti-static, which also maximizes the use of precious wood resources.
Wallong uses unique color mixing, hot pressing, and post-processing processes to make the surface of co-extrusion WPC decking have a softer, more realistic, and simulated high-end solid wood effect, and have a longer service life. Wallong co-extruded wood plastic flooring uses a special co-extrusion extruder with high back pressure, small shear, and good plasticizing and mixing. It makes the welding and coating of the core layer and the co-extruded surface layer inside the wood plastic better, so the surface of the co-extruded wood plastic floor has a realistic wood texture, strong weather resistance, high surface hardness, not easy to be scratched, and higher water absorption rate low. In addition, the surface of the co-extruded layer has a 3D relief texture, which also adds anti-skid and aesthetic properties to the co-extrusion WPC decking.

Wood plastics on the market commonly suffer from fading, mildew, surface cracking, etc., which are fatal flaws of wood plastic products. Wallong's co-extruded wood plastic flooring seals the wood plastic core material, which can fundamentally and effectively solve these problems. Since the co-extruded layer on the surface completely separates the wood-plastic substrate from the external environment, its weather resistance and aging resistance are greatly improved.
Wallong's unique full-covering technology and multiple protections allow outdoor wood-plastic products to completely eliminate problems such as fading, water absorption, cracking, and deformation. Because the surface layer is covered with a polymer co-extrusion layer, co-extrusion WPC decking has excellent waterproof properties outdoors, which can effectively prevent moisture from intruding and damaging the core layer of the floor. Even if it is used outdoors for a long time, water droplets falling on the co-extrusion WPC decking will form water droplets on the floor surface and will not spread or penetrate into the core layer of the floor.
When traditional wood-plastic composites are extruded at high temperatures, the lignin in the wood powder degrades, causing the color of the wood-plastic composites to darken. However, this color becomes darker and unstable, and the color will gradually fade under the action of ultraviolet rays. Adding antioxidants and light stabilizers will not achieve the desired effect, and the wood-plastic composite material will also fade. The Wallong co-extruded wood-plastic floor has an outer layer of polymer material that is highly wear-resistant, weather-resistant, mildew-proof and insect-proof, and its water absorption rate is almost "zero", which not only ensures the density and performance of the material but also does not produce "brittleness" shortcomings.
