Wood plastic material contains huge economic and environmental benefits

Thermoplastic wood plastic composite (WPC) is a modified thermoplastic material made by wood fiber or plant fiber filled, reinforced, and processed by hot pressing and melt extrusion. In recent years, with the depletion of global resources, the awareness of social environmental protection has been rising day by day, and higher demands have been placed on the application of wood and petrochemical products. In this context, wood-plastic composite materials can not only exert the advantages of various components in the materials, but also overcome the limitations due to low strength, high variability, and low elastic modulus of organic materials, and can be fully utilized. Waste wood and plastics reduce environmental pollution.

At present, products that increase the added value of materials have received more and more attention. Now research focuses mainly on the use of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and other thermoplastics and wood flour, plant straw powder, plant seed shells and other wood flour Material is raw material, and the composite material made by extrusion, injection molding, and compression molding. From the perspective of raw materials for production, raw materials for wood-plastic composite materials can use various waste plastics, waste wood, and residues of crops. Therefore, the development and widespread application of wood-plastic composite materials will help to reduce the pollution of plastic waste, and it will also help reduce the pollution of agricultural wastes brought to the environment.

The production and use of wood-plastic composite materials will not emit volatiles that harm human health to the surrounding environment. The materials themselves can also be recycled. It is a brand-new green environmental protection product and is also an ecologically clean composite material. Therefore, the research on the preparation and processing of wood-plastic composites contains enormous economic and environmental benefits.
