Wood-plastic composite materials favored by the international market

Modern society, wood-plastic composite materials no longer a novelty. As early as in the 1980s, when the first appearance of the wood-plastic composite material facing confrontation sagging, deformation, division and ruptured a major challenge.

The latest report shows, the Hackwell Group predicts that by 2015, the demand for wood-plastic composite materials will reach 36 million tons, an annual average of 13% growths. During 2005-2012, despite the global economic crisis, but the prospects for wood-plastic composites are still good. The world’s leading timber company the Sonae Industria claims, the introduction of wood-plastic composites, which are a powerful enough to replace glass fiber short fiber applications.

What is the wood-plastic material, why has such a “magic” color? In fact, natural fiber reinforced thermoplastics abound in modern life. Many crops such as rice, wheat, kenaf, hemp can be used as a natural filler, used in different industries. We need to recognize that the construction industry is in very bad condition, how can we create more high-quality products have become particularly important. To create a New World of the timber industry, to integrate into the plastic come. Medium density fiberboard become appear to bring about a new direction for the timber market.

Medium density fiberboard in small-diameter logs, harvesting, processing residues, as well as non-wood plant fiber raw materials, urea-formaldehyde resin or other suitable adhesive is applied to the dried slices, cooking, fiber separation, made by hot pressing after a kinds of artificial board. Its density is usually in the 500-880kg / cubic meter range, the thickness of 2-30mm. WPC is the timber with more than 50% of polyethylene, polypropylene, and polyvinyl chloride is mixed into a new wooden material through the twin-screw extruder, the plastic of the thermoplastic resin matrix fibers is evenly distributed in the material. There is no specific dosage and equipment requirements.

Wood-plastic composite materials have another advantage. The avoid the simple wood dust problem. In the production process, to reduce and avoid the danger of explosion of the combustible dust.
