Thermoplastic Properties Of The Wood Plastic Composite (WPC) Materials

Wood plastic composite(WPC) material is a modified thermoplastic material, which is made of wood fiber or plant fiber filling, reinforcement, hot pressing composite material, melt extrusion and other processing methods.

Global resources are shrinking, higher requirements are put forward for the application of wood and petrochemical products. In this case, WPC materials can not only give full play to the advantages of the material itself, but also overcome the limitations of the use of ordinary wood due to low strength, large variability and low elastic modulus of organic materials, and can also make full use of waste wood and plastics to reduce the pressure on the environment.

At present, more and more attention has been paid to products that increase the added value of materials. Nowadays, the research focus is mainly on thermoplastics and wood flour, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and wood flour, plant straw powder, plant seed shell and other raw materials, extrusion, injection molding, compression molding composite materials. From the perspective of production raw materials, the raw materials of plastic-wood composite materials can be used for various waste plastics, waste wood and crop residues.

Therefore, the development and wide application of plastic-wood composite materials will help reduce the pollution of plastic waste, and also help reduce the environmental pressure caused by agricultural waste incineration.

Wood Plastic Composite materials will not affect the surrounding environment, nor will it emit volatile substances harmful to human health. The material itself can also be recycled. It is also a brand-new green environmental protection product and ecological clean environmental protection material. Therefore, the research on the preparation and processing of plastic-wood composites has great economic and environmental benefits.
