WPC hotspot

Thermoplastic Wood Plastic Composites (WPC) is the use of wood fiber or plant fiber filling, reinforced by pressing compound melt extrusion and other modified thermoplastic material made of different processing methods. In recent years, with the world's resources are depleting, social awareness of environmental protection has become increasingly high, wood and petrochemicals applications put forward higher requirements. In this context, the WPC material that can not only play the advantages of each component, to overcome limitations due to low use of wood strength, great variability and low modulus of elasticity of organic materials caused, but also take advantage of wood and plastic waste, reduce environmental pollution. Currently, value-added products improve the material more and more people attention.best outdoor timber decking

Now research focus mainly concentrated in the polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and other thermoplastic and wood flour, straw powder plant species from shells and other wood flour as raw materials, composite materials by extrusion, injection molding, compression molding made of. From the production of raw materials, the raw WPC can be all kinds of waste plastics, waste wood and crop residue. Therefore the development and wide application of wood-plastic composite materials help slow pollution plastic waste, but also helps to reduce the burning of agricultural wastes to the environment pollution. Production and use of wood-plastic composite materials are not hazardous to human health and the environment exudes volatiles, the material itself can be recycled, is a new green products, but also an ecologically clean composite.aluminium composite panel cladding west yorkshire

At present, foreign countries have to add additives WPC were studies, such as to improve the strength of coupling agents, lubricants, light stabilizers, antimicrobials, water, chemical blowing agents and the like. Development of these ancillary products has caused concern to many scientists, and has made some progress. U.S. Patent reports, adding the dye in wood composite materials may make it long-lasting anti-fading capability, and has been the advent of color WPC. Research also shows that hydrocarbon quaternary ammonium salts such as carboxylate, sulfate, etc., can have antibacterial properties of wood-plastic composites. These studies will further expand the scope of application of WPC. Further, the surface treatment of wood flour radiation technology has become a new hotspot.2x4 composite studs
