Wood plastic composite material is a new kind of composite material which is booming at home and abroad in recent years. It refers to the plate or profile which is produced by using polyethylene, polypropylene and PVC to replace the usual resin adhesive and mixing with more than 50% wood powder, rice husk, straw and other waste plant fibers into a new wood material, and then through extrusion, molding, injection molding and other plastic processing technologies.
It is mainly used in building materials, furniture (WPC railings), logistics packaging and other industries. The extruded wood plastic composite board is a board which is formed by hot extrusion after mixing plastic and wood powder in a certain proportion.
1. Good processing performance
Wood plastic composite material contains plastic and fiber, so it has the same processing performance as that the wood has. It can be sawn, nailed and planed. It can be finished by using woodworking tools, and the nail holding force is obviously better than other synthetic materials.
The mechanical properties are better than that of wood materials. The nail holding force is generally 3 times than that of wood and 5 times than that of particleboard.
2. Good strength performance
Wood plastic composite material contains plastics, so it has better elastic modulus. In addition, it contains fiber and is fully mixed with plastic, so it has the same physical and mechanical properties as hardwood, such as compression resistance and bending resistance, and its durability is significantly better than ordinary wood materials. The surface hardness is high, generally 2-5 times than that of wood. So, it is often used to make WPC railings because of its durable feature.
3. Water and corrosion resistance, long service life
Compared with wood, wood plastic materials and their products are resistant to acid and alkali, water and corrosion, and do not breed bacteria, and are not easy to be mothed and do not grow fungi. In addition, they also enjoy long service life, which is up to more than 50 years.
