Abstract: This paper introduced the formulation, compositions and traditional processing methods of wood plastic composites (WPC) and also analyzed the latest three processing technologies, in which the subcritical fluidassisted reactive extrusion technology was considered as a novel processing method for the preparation of WPC. These technologies provide a new route for the preparation of highperformance WPC.
