Wood plastic composite bring huge economic benefits and environmental benefits: thermoplastic wood plastic composite (WPC) is the use of wood fiber or fiber filling, strengthen, via hot pressing composite, melt extrusion made of different processing methods, such as modified thermoplastic materials. Increasingly dried up in recent years, along with the global resources, social and environmental consciousness became more and more high, application of wood and petrochemical products put forward higher requirements. In this context, the wood-plastics composites can play advantage of the material of each component, overcome because of timber intensity is low, a large variability, and organic material use limitations caused by low modulus of elasticity, and can make full use of scrap wood and plastic, reducing environmental pollution.
