Secondly, the technical backwardness. Yi-Chi Chang pointed out that, at present, the domestic research disjointed serious, mutual exchanges of relevant research institutions and enterprises of WPC less, lack of effective communication, coordination and cooperation, so that the process of industrialization of some research has been slow. Moreover, the domestic technical talent scarcity, in the field wood plastic composite deck tiles contractor johor bahru of WPC almost no technical innovation, some products require a higher performance and condition of WPC products have not been large-scale development, making China WPC technology lagged far behind the developed countries. Again, products of different specifications clutter, lack of appropriate technical standards. Yi-Chi Chang pointed out that, at present, products of different specifications of WPC is more messy, but also in terms of product technology is neither an industry standard, and no national standards, the production company's product quality is not uniform evaluation, allowing companies to improve their product warm quality is not high. And now some of the organizations outside the industry tries to join the landscape interlocking outdoor wooden tiles Hastings WPC standard-setting, but also exacerbated the confusion status of domestic wood-plastic composite products, the development of wood-plastic composites industry is very unfavorable. In addition, the market is not in place to promote industrial development issues are also WPC facing our country. Yi-Chi Chang pointed out that WPC is an emerging science and technology products, where they are to understand the lower level, and now the information varied, complex, people's understanding of WPC information was chaotic. Currently, the wood products in the domestic market where to buy wood panel in singapore has not been promoted a large area, so that the growth of WPC market is relatively slow, it is not conducive to the rapid expansion of domestic wood-plastic composite materials industry.
