Selection of raw materials according to the application, the production of Wood Plastic Composite is usually divided into three types of hollow, solid and structured. Hollow load can be used in small trestle above the general surface and fence wood panels used in the physical facilities of the heavier load above. Production of  WPC Floor with wood has some limitations, such as temperature and moisture content of the processing problems. Nevertheless, and other substrates, such as mineral material than lower plate processing and handling equipment wear. And compared to traditional wood products, wood panels as well as a number of advantages can be arbitrarily strong and durable water-resistant paint, will not easily bend, break and fracture of wood-plastic made ​​from recycled materials board itself can still be recovered, are environment-friendly materials and WPC Wall Panel with the same processing capacity of the maintenance workload is low. The disadvantage is compared with other materials, production costs higher than the finished board about twice the weight of wood, wood board density is 0.95-1.46, while the wood density is 0.35-0.59; wood wood board determines the content of the degree of decay, that the wood content more easily the higher the degree of corrosion. And production of pure wood products compared to the inadequacies in the following several times higher in energy when the structure of materials can not use ultraviolet light will reduce the service life. In order to ensure that the wood board in line with standards and user requirements, the selection and preparation of raw materials becomes very important. It is noteworthy that no special materials are to be designated as wood board material. Selection of raw materials must be availability, economic factors and products in the market needs to decide. Polymers such as wood panels can be high and low density polyethylene or polypropylene, wood can be a different species of wood flour or wood fiber. However, the stability of wood and plastic is very important, such as cleanliness, physical properties and moisture content. The use of clean raw materials and waste wood board production technical problems encountered will be different, because the performance by the type of raw materials, waste handling and recency of great influence.
