Wood-plastic composite

Wood-plastic composites (WPCs) are produced by thoroughly mixing ground wood particles and heated thermoplastic resin. The most common method of production is to extrude the material into the desired shape, though injection molding is also used. WPCs may be produced from either or recycled thermoplastics including HDPE, LDPE, PVC, PP, ABS, PS, and PLA.
