The process of WPC material?

With the research and development of wood-plastic composite materials, the plastic raw materials for the production of wood-plastic composite materials include polyvinyl chloride and PS in addition to high-density polyethylene or polypropylene. The process has also been developed from the earliest single-screw extruder to the second-generation conical twin-screw extruder, and then to the initial granulation by the parallel twin-screw extruder, and then extruded by the conical screw, which can make up for the difficulty of plasticization. , poor aging resistance, poor creep resistance, poor color consistency and durability and tensile strength, etc.

Scope of application
One of the most important uses of wood-plastic composites is to replace solid wood in various fields, of which the most widely used is in construction products, accounting for 75% of the total wood-plastic composite products.
