Wood plastic composite material is a kind of reversible recycling using sawdust, bamboo chips, rice husk, rice chaff, peanut husk, cotton straw and other low-plant biomass fibers as the main raw materials, using the principle of macromolecule interfacial chemistry and the characteristics of plastic filling and modification, mixing a certain proportion of plastic base materials, processing and forming by special technology. It covers a wide range, has a lot of varieties and diverse forms and structures.

At present, there are different appellations for it at home and abroad, and it is also called plastic wood, environmental protection wood, science and technology wood, recycled wood, aggregate wood and so on. It has all the characteristics of wood processing.

WPC material has five characteristics:

1. Resource utilization of raw materials: its biomass material is mainly making use of the waste, which has a wide range of sources and low value; the plastics composition requirements are not high, and new, old or mixed materials can be used, which fully reflects the comprehensive and effective utilization of resources.

2. Plasticizability of products: Wood plastic products are synthetic products. The process and formulation of products can be randomly adjusted according to the requirements of use, so that materials with different properties and shapes can be produced. The utilization ratio of profiles is close to 100%.

3. Environmentally friendly of the use: Wood and plastic base materials and their commonly used additives of the wood plastic products are environmentally friendly, non-toxic and harmless, and their production and processing process will not produce toxic side effects, so they do not constitute any potential danger for human body and the environment.
