Wood Plastic Composites (WPCs) are composite materials made of wood fiber or wood flour and thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA).� They can also contain other ligno-cellulosic and/or inorganic filler materials.
WPCs are crucial and potential engineering wood products that have been extensively employed in the fields of landscape, transportation, municipal engineering, and building construction.� They have gradually been used to replace conventional wood-based composites.� WPCs are mainly produced by the thermoplastic polymers and the biomass particles and fibers from forestry and agricultural wastes (wood, bamboo, straw, stalk, husk, and bast).
The WC line of wood-plastic composites combines the pleasing look of wood with the functionality and manufacturing ease of plastics.� These composites blend fine wood particles with renewable, biodegradable, reclaimed, recycled, or virgin plastic materials to make firm, smooth pellets for convenient handling and further processing.� The wood fibers are obtained from waste materials generated by lumber manufacturers, which are then processed to produce a consistent reinforcing product.
