What Are The Main Characteristics Of Wood-plastic Composites?

Wood-plastic composite material is a new type of composite material, which refers to the use of polyethylene, polypropylene, polyvinyl chloride, etc., instead of the usual resin adhesive, and more than 50% of wood flour, rice husk, straw, and other waste plant fibers are mixed into a new The wood materials are extruded, molded, injection molded and other plastic processing techniques to produce plates or profiles.

Mainly used in building materials, furniture, logistics packaging, and other industries. A board that is formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called an extruded wood-plastic composite board.

The basis of wood-plastic composite material is high-density polyethylene and wood fiber, which determines that it has certain characteristics of plastic and wood.

1) Good processing performance

Wood-plastic composite materials contain plastics and fibers, so they have similar processing properties to wood. They can be sawed, nailed, and planed, and can be completed with woodworking tools, and the nail-holding power is significantly better than other synthetic materials. The mechanical properties are better than wood materials. The nail holding force is generally 3 times that of wood and 5 times that of particleboard.

2) Good strength performance

The wood-plastic composite material contains plastic, so it has a good elastic modulus. In addition, because it contains fiber and is fully mixed with plastic, it has physical and mechanical properties such as compression resistance and bending resistance equivalent to hardwood, and its durability is significantly better than ordinary wood materials. The surface hardness is high, generally 2-5 times that of wood.

3) It has water resistance, corrosion resistance, and long service life

Compared with wood, wood-plastic materials and their products are resistant to strong acid and alkali, water, and corrosion, and do not breed bacteria, are not easy to be eaten by insects, and do not grow fungi. The service life is long, up to more than 50 years.

4) excellent adjustable performance

Through additives, plastics can undergo changes such as polymerization, foaming, curing, modification, etc., thereby changing the density and strength of wood-plastic materials, and can also meet special requirements such as anti-aging, anti-static, and flame retardant.

5) It has ultraviolet light stability and good colorability.

6) Its biggest advantage is to turn waste into treasure, and it can be 100% recycled and reproduced. It can be decomposed and will not cause "white pollution". It is a truly green and environmentally friendly product.

7) Wide sources of raw materials

The plastic raw materials for the production of wood-plastic composites are mainly high-density polyethylene or polypropylene. The wood fiber can be wood flour, grain bran, or wood fiber. In addition, a small number of additives and other processing aids are required.

8) It can be made into any shape and size according to needs.
