What is wood plastic composite products

What is wood plastic composite products

People have affinity for wood, home decoration is inseparable from the wood. But the wood itself is also shortcomings, easy to shrink cracking, water easily variable, wet and easy to mold, the case of fire easy to burn, if made of plywood made of wood, which will also cause pollution of the indoor formaldehyde.

In foreign countries, after more than 10 years of research, development and industrial applications, wood-plastic composite materials have formed a new industry. Wood-plastic composite materials to wood flour, agricultural straw powder and other plant fiber and plastic as the main raw material, the use of advanced processing technology, and the product can be recycled and re-use. From the sense of view, wood-plastic material has a good wood texture, moisture resistance, good coloring, insulation insulation corrosion, mechanical properties than the simple wood material 10 times higher, an ideal alternative to natural wood. Only in North America, the annual output of more than 40 million tons, the output value of 1.2 billion US dollars. European industrial developed countries, Japan, Australia, are also in the development of wood and natural fiber composite materials products. Mainly to waste plastic and branches tree branches powder, agricultural straw powder and other plant fiber as raw materials, made of products are widely used in packaging, gardens, transportation, construction, garage and other fields.

PVC wood powder composite material developed rapidly, with its high toughness, low cost advantage is gradually replacing the traditional wood products; but because the PVC wood powder composite material is wood powder composite, so that the ductility and impact resistance decreased, the material Brittle, density than traditional wood products nearly 2 times, limiting its wide use. In order to eliminate these shortcomings, the impact modifier is usually used to improve the impact properties, but to improve the ductility and reduce the density is almost invalid.
