Wood-plastic composite - Wikipedia

Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and of production is to extrude the material into the desired shape, though injection molding is also used. WPCs may be produced from either virgin or recycled thermoplastics including HDPE, LDPE, PVC, PP, ABS, PS, and PLA.
