Abstract: Recent research progress at home and abroad on Poly(Vinyl chloride)/Wood flour(PVC/WF) composites was reviewed. The new equipments and techniques, including planetary roller twin-screw extruders, conical twin-screw extruders with a dry device and WoodTruder? extrusion system in which WF was conveyed to extruder without predrying and preblending were introduced. The research advance on additives used in PVC/WF composites such as lubricants, impact modifiers, plasticizers and compatibilizers was summarized. Technologies related to microcellular foaming and environment protecting were introduced and evaluated. Finally, development trend of PVC/WF composites was expected.

Key words: poly(vinyl chloride), wood flour, composites, developing trend
