Foamed WPC Discussion Wood-plastic composite materials; foam; pvc 1 at why - Development background WPC (WPC) is a wood as the main raw 8 foot composite railings manufacturer material (in the form of sawdust, wood chips, bamboo shavings, rice husk, wheat straw, soybean hulls, peanut shells , bagasse, cotton stalks, etc.), after appropriate treatment it with a variety of plastics (thermoplastics for WPC mainly polyvinyl chloride (PVC}, polyethylene PEA, polypropylene (PPS), polyphenylene ethylene (PST), polymethyl methacrylate cool (CPMM), and polyethylene (PE),.
polypropylene (PP), polystyrene (PS), etc.) by mixing and adding special additives, such as coupling agents, dispersing agents, plasticizers, lubricants and other processing aids, high temperature, extrusion, molding and other processes made of a new composite material is a high outdoor green building material performance, high value-added green composite materials. the selected plastic can be a new material, it can be recycled waste plastic, added a rich source of plant fiber, low cost, and can be recycled WPC combines the dual characteristics of wood and plastic: easy for secondary processing, Non-toxic, not afraid of insects, water, and other reusable plastics with respect to, its toughness, impact strength and flexural strength will be reduced; and relatively natural wood, usually several times the density and therefore the timber.
its application subject to certain restrictions. in order to improve the mechanical properties of wood-plastic composite materials, and the cost of reducing the density of the composite material, porous foam WPC in recent years become a hot wood-plastic composite cheapest warrenty fence panels on the market France materials research. now prepared PE, PP, PVC, PS, PUR-based and other types of wood-plastic composite plastic foam, wherein foam plastic PVC-based WPC its chemical stability, high strength, acid and alkali resistance, water immersion, flame retardant and low cost is widely used.
