Wood plastic is in the wood fiber and other natural fibers wrapped around a layer of plastic layer, wood plastic water absorption is very low. Very suitable for waterfront landscape. Wood and general wood comparison, the proportion of wood plastic is much larger, usually in the 1.1 to 1.18, and the general proportion of wood 0.4 ~ 0.7, even the greater proportion of hardwood, the proportion of only about 1.0. So the same volume of wood under the plastic to be much heavier. Later, in order to reduce the weight of wood-plastic products, take the foam, change the profile shape, design structure and other methods.
Foreign wood-plastic industry to North America as the representative of North America is the world's fastest growing wood and plastic composite materials and the largest amount of the region, mainly for the style of the outdoor buildings, its wood products and their manufacturing technology are not the pursuit of fine The Over the past 10 years, the growth rate of the US wood plastic market are maintained at 10% or more, especially in the past five years, particularly fast growth in 2009, wood plastic materials production and sales of about 70 million tons. Now the United States about 50 or so wood-plastic enterprises, has formed a complete industrial chain, which is characterized by large-scale, high yield, with an annual output of more than 10,000 tons in general.
China's wood is a very young industry, it grew the history of more than a decade, no matter from which side, are still immature, the Chinese market compared with the North American market, wood-plastic composite materials and finished products growth Quite a lot of space. At present, the domestic wood-plastic composite materials design, manufacturing has reached the international advanced level, many products have been exported abroad.
