Introduction To The Characteristics Of Wood-Plastic Composites

Wood-plastic composites are based on high density polyethylene (HDPE) and wood fibers, which determine their own properties of plastics and wood.

1) Good processing performance, wood-plastic composites contain plastics and fibers. Therefore, wood-plastic composites have similar processing properties as wood. They can be sawn, nailed and planed. They can be completed by using woodworking tools, and the nailing force is obviously better than other synthetic materials. Mechanical properties are superior to wood materials. The nailing force is generally three times that of wood and five times that of particleboard.

2) Wood-plastic composites have good strength and elastic modulus because they contain plastics. In addition, due to the inclusion of fibers and the full mixing with plastics, it has the same physical and mechanical properties as hardwood, such as compression and bending resistance, and its durability is significantly better than that of ordinary wood materials. Surface hardness is high, usually 2 - 5 times of wood.

3) It has water resistance, corrosion resistance and long service life. Compared with wood, wood-plastic materials and products can resist strong acid and alkali, water resistance, corrosion resistance, and do not breed bacteria. They are not easy to be moth-eaten and grow fungi. Long service life, up to 50 years.

4) Excellent adjustable properties. By means of additives, plastics can be changed in terms of polymerization, foaming, curing and modification, so as to change the density and strength of wood-plastic materials. It can also meet the special requirements of anti-aging, anti-static, flame retardant and so on.

5) It has the stability of ultraviolet light and good coloration.

6) Its greatest advantage is to turn waste into treasure, and can be recycled and reproduced 100%. Can be decomposed, will not cause "white pollution", is a real green environmental protection products.

7) There are a wide range of raw materials. The main raw materials for producing wood-plastic composites are high density polyethylene or polypropylene. Wood fibers can be wood flour, rice bran or wood fibers. In addition, a small amount of additives and other processing aids are needed.

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