POLYPROPYLENE/WOOD COMPOSITES

Wood-plastic composites (WPCs) are composite materials made of wood fiber/flour and plastics. In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials. WPCs can also be referred to as natural fiber plastic composites or natural fiber reinforced plastics. They are used in outdoor deck floors, railings, fences, landscaping timbers, cladding and siding, park benches, molding and trim, window and door frames, and indoor furniture.Manufacturers claim that wood-plastic composite is more environmentally friendly and requires less maintenance than the alternatives of solid wood treated with preservatives or solid wood of rot-resistant species. These materials can be molded with or without simulated wood grain details.
