WPC Profile

        WPC is a new material to wood and plastic composite according to certain technical processes and the formation of a thermosetting plastic resin and a thermoplastic resin divided into two categories.
        Phenolic resins, urea-formaldehyde resins, isocyanates and epoxy thermosetting resins are commonly used in the forest products industry, the thermoplastic resin refers repeatedly after heat can melt, after cooling can be hardened by forming a polymer material such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, a thermoplastic resin can be reused, while the WPC we commonly refer mainly refers to wood and thermoplastic resin composite products.
        According to different processing technology and products can be existing wood-plastic composite materials are divided into four categories, which are impregnated wood plastic composite material, plastic composite wood, wood materials filled or reinforced plastic composite material, wood fiber / synthetic fibrous nonwoven composite materials and wood-plastic composite wood-based panels, most of the material goods which have been widely used in automotive interior parts, electrical materials, house wall materials, construction and decoration, furniture, vertical injection molding machines.
        Wood plastic composite material impregnated wood-based polymer impregnated with other organic monomers or prepolymers, and made caused by physical and chemical methods and the modified polymeric material, also known as WPC, the trade name strengthen the wood, research and application in this regard earlier, but the product has not been widely used reason to give mainly the cost is too high, wood fiber / synthetic nonwoven composite material is non-woven airlaid forming technology with the wood fibers synthetic fibers, mainly polyester fibers, polypropylene fibers and other additives into the web, and then molded into a final product, the material products are mainly used in automotive interior parts, such as instrument panels, door guard, rear shelf , sunroof, vertical injection molding machine, Chinese Academy of Forestry Wood Industry Research Institute Taskforce lignocellulosic composite material, this material began in the early 1990s in Europe and the Americas in the automotive industry applications.
        China began research in this regard from the early 1990s, has now also achieve initial industrialization, this aspect of vertical injection molding machine technology is constantly developing, product use and more widely, not only for the automotive industry, the technology products are also quietly entered the building and other industries, is used as wall materials and green houses and solid earth ground plant raw material is filled with a material of wood or reinforced plastic composite material mainly refers to the preparation method of a vertical injection molding machine for plastic products The main processing or plastic wood composite products for the continuous phase, the class WPC products have been about forty years of research and development history, earlier onset of polypropylene for automotive interior parts of wood Powder board is of such products, in recent years other wood materials have also filled plastic composites used in production and daily life, the most important application of polypropylene powder board automotive interior parts, PVC Wood Composite Door polyethylene wood flour composite porch products.
        Wood-based plastic composite wood-based panels are plastic binder, wood-based panel production technology products for the processing method for producing wood-plastic composite material, the material based on the characteristics of thermoplastic adhesives, wood materials content, and wood materials You can have a variety of forms, can be fibrous state, shavings state, may also be the board state its products are generally large format flat or molded products, its greatest feature is environmental protection, on the one hand, the use of plastic is recycled waste plastic, are recycling, wood-plastic composite panels prepared on the one hand there is no free formaldehyde release, in addition, the water resistance of wood-plastic composite materials are also much better than ordinary wood-based panels, wood-plastic composite panel products can be used for pallets, cement template field, decorative materials, good prospects.
        WPC has become one of the world's hot spots and vertical injection molding machine plastic timber processing and utilization of research in the field of wood-plastic composite materials research on popular attention, many foreign universities, research institutions and enterprises are engaged in wood research and development of composite materials, which studies the United States, Japan, Canada and Germany and other countries more but also more successful, and now has a special international conference on the topic held WPC and have related papers published annually on wood plastic composite materials research reports are also many recent years, the forest products industry in the famous journal, Forest Products Journal, and every year there are 35 studies on the WPC was published, other periodicals such as, Wood and Fiber Science also Thus, research on domestic than foreign WPC would be late, but the end of the 1980s and early nineties has caused concern of the majority of researchers, then there are more and more About WPC aspects of studies and foreign review reports in recent years have been like a wood fiber / synthetic fiber composite engineering materials, wood-plastic composite particleboard and other research, and research on wood-plastic composite materials are also more and more deeply.
