Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and . Chemical additives seem practically "invisible" (except mineral fillers and pigments, if added) in the composite . A large variety of injection molded parts are also produced, from automotive deck panels to cell phone covers.
