What Is a Wood-Plastic Composite?

Wood-Plastic Composites (WPC) is a new type of composite materials that has flourished in recent years at home and abroad. It refers to the use of polyethylene, polypropylene, and polyvinyl chloride, instead of ordinary resin adhesives, and more than 50% Wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed through extrusion, molding, injection molding and other plastic processing processes to produce boards or profiles. Mainly used in building materials, furniture, logistics and packaging industries. A board made by mixing plastic and wood powder in a certain proportion and hot-extruded is called an extruded wood-plastic composite board.

WPC composites are based on

With the development of wood-plastic composite materials, in addition to high-density polyethylene or polypropylene, the plastic raw materials for the production of wood-plastic composite materials include polyvinyl chloride and PS. Craftsmanship

The different names of "wood-plastic" and "plastic-wood" bring too much trouble to the production and use personnel, especially for those who are in contact with the product for the first time. I think it is more appropriate to call it "plastic wood" uniformly.

There are four reasons:

The first is that the material is mainly used to replace wood, which is a kind of "wood" synthesized from plastic and wood fibers;

The second is that most of the wood fiber content in plastic-wood products produced in China is greater than 50%, mainly wood;

The third is the meaning of using wood fiber as the basic raw material in the definition of the US standard, "wood" is the main body;

The fourth is the alias of this material at home and abroad, such as "plastic wood", "environment-friendly wood", and "Ain wood" in Japan, which emphasize "wood", so it is more reasonable to call it "plastic wood".
