Abstract	The paper presents results of our recent studies on the viscoelastic characteristics of thermoplastic composites filled with 30 wt.% of wood flour (WF), as a part of the foaming program. PP, HDPE and PVC were used as polymer matrices. Melt processability has been characterized by MFI tests in temperature of 180°C, 190°C and 200°C. It has been shown that the composites based on PP and PVC were easier flowing than HDPE in that range of temperature. Melt viscosity results suggested a thermal degradation of PVC. However, wood flour exhibited a stabilizing effect on PVC in PVC/WF composites. Melt strength tests have shown that the compatibilized PP/WF composite should be useful for foaming. Set of experiments with a chemical blowing agent has been performed in the single-screw extruder, which confirmed that supposition.
