ASA-PVC co-extruded wood is extruded from two extruders, PVC plastic wood substrate and ASA co-extruded coating material, and then through the co-extrusion compound die, the ASA coating layer adheres when extruded with the substrate.
On the surface of the substrate, achieve the purpose of coating the substrate. Co-extrusion coating properties are also different due to the different materials used in the coating. Currently, the co-extruded coating materials mainly include PMMA, PVC and ASA.
With the global depletion of forest resources and the increasing awareness of national environmental protection, the wood-plastic industry has developed well, and ASA-PVC co-extruded wood has also been widely used in gardens, transportation, construction, home improvement, cars and boat interiors.
