Technology Of Wood-plastic Composites

- May 13, 2018-

With the development of wood-plastic composites, plastic raw materials for the production of wood-plastic composites, in addition to high-density polyethylene or polypropylene, there are PVC and PS.  The process was also developed from the earliest single screw extruder into the second generation conical twin-screw extruder, and then by the parallel twin-screw extruder initial granulation, and then by the conical screw extrusion molding, can make up for difficult plasticizing, poor anti-aging resistance, poor creep resistance, color consistency and durability and tensile strength. China's many research institutes and at Hanyong plastic new materials after years of research and development and accumulation, the manufacture of WPC materials can fully reach GB/T 24137 and ASTM D7031; ASTM D7032;bs DD cen/ts 15534-3 requirements.
