As early as decades ago, the United States began the research and extrusion of wood-plastic composites, but because the processing technology is not mature, compared with plastic and pure wood products, there are many performance defects, wood-plastic composites have not developed rapidly.
With the breakthrough of industrial technology, the new processing technology has greatly improved the performance of wood-plastic composites, and the market of wood-plastic products has opened rapidly. The large-scale industrial wood-plastic composite extrusion began in the 1980s. With the rapid growth of automobile industry, the demand for automotive interior accessories increased unprecedentedly, and then the wood-plastic composite materials continued to grow steadily. With the further development and excavation of the market, wood-plastic composites are more and more used in real estate, public facilities and so on. In 1991, the International Conference on Wood-plastic Composites was held in the United States. In the decade of the 1990s, the wood and plastic industry in the United States has made great progress, with annual growth of more than 10 percent. After more than a decade of development, the United States has more than 50 wood-plastic enterprises with an annual output of more than 10,000 tons. Among them, the largest companies have been listed on the New York Stock Exchange, forming a complete industry from product development, raw material collection, equipment manufacturing, mold research and development, finished product production to market marketing.
The overall development of European wood-plastic industry is not as good as that of North America, but it has accelerated in recent years. Wood and plastic enterprises are not many, the output and scientific and technological level are commensurate with Chinese enterprises, but they have strong equipment manufacturing capacity, and their development potential can not be underestimated. European requirements for wood and plastic materials are more delicate, the demand for variety and color is also higher than North America, interior decoration and outdoor buildings go hand in hand, but the use of technology and commodity market is not very mature, there is room for rapid growth. Due to geographical reasons and awareness of environmental protection, wood-plastic materials are widely used and the quality of products is good. Japan's wood-plastic R & D institutions, after more than 10 years of efforts to develop high-quality wood-plastic materials. Its products have natural wood color and texture, and have been widely used in the field of housing construction and interior decoration. It is one of the highest quality products in the world at present. It represents the quality level and development trend of replacing natural wood with wood-plastic materials. Foreign development status:
North America is the world's largest wood and plastic market, according to special reports, North America alone in 2001 annual consumption of more than 320000 tons. It is expected to increase at a double-digit rate by 2005, which will be more than double the amount used in 2001. Among them, the United States has been in the forefront of industry research and development and market development. In Europe, the development of wood-plastic composites is strong, the technology has reached the stage of co-extrusion, in the furniture manufacturing industry, has been maintaining sustained growth, is about to occupy a dominant position. In addition, Japan's development is also in the international leading level.
