What is WPC And what industries can it do?
Wood-Plastic Composites (WPC) refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesive, with more than 50% of wood flour, rice husk, straw and other waste plant fibers mixed into a new wood material, and then extrusion, molding, injection molding, and other plastics processing technology, the production of panels or profiles. Mainly used in building materials, furniture, logistics and packaging industries. Plastic and wood powder mixed according to a certain proportion of hot extrusion molding plate, called extrusion wood-plastic composite panels.
Wood-plastic composite materials based on high-density polyethylene and wood fibers, determines its own plastic and wood with certain characteristics.
(1) good processing performance
Wood-plastic composite materials containing plastics and fibers, therefore, has a similar processing performance with wood, can be laminated, can be wrapped in a variety of film, can be sawed, can be nailed, can be planed, the use of carpentry equipment can be completed, and the nail holding power is significantly better than other synthetic materials. Mechanical properties are better than wood materials. Nail strength is generally 3 times that of wood, 5 times that of particleboard.
(2) good strength properties
Wood-plastic composites contain plastic, which has a good modulus of elasticity. In addition, because of the fibers contained within and fully mixed with plastic, and thus has a comparable hardwood compression, bending and other physical and mechanical properties, and its durability is significantly better than ordinary wood materials. High surface hardness, generally 2 - 5 times that of wood.
(3) has water resistance, corrosion resistance, long service life
Compared with wood, wood-plastic materials and products can resist strong acid and alkali, water, corrosion resistance, and does not reproduce bacteria, not easy to be moth-eaten, not long fungi. Long service life, up to 50 years or more.
(4) Excellent adjustable performance
Through the additives, the plastic can be polymerization, foaming, curing, modification and other changes to change the density of wood-plastic materials, strength and other characteristics, but also to achieve anti-aging, anti-static, flame retardant and other special requirements.
(5) It has ultraviolet light stability and good coloring.
(6) Its biggest advantage is to turn waste into treasure, even if the use of PUR glue pasted film can be 100% recycled back to production. It can be decomposed and will not cause "white pollution", which is a real green product.
(7)Wide source of raw materials
Production of wood-plastic composites of plastic raw materials is mainly high-density polyethylene or polypropylene, wood fiber can be wood flour, grain bran or wood fiber, in addition to a small number of additives and other processing aids.
(8) According to the need, can be made into any shape and size.
