    Abstract

    Wood-plastic composites (WPC) typically include cellulose-based fine waste. WPC s are less susceptible to environmental effects compared to wood itself. However WPC s are not totally insensitive to environmental effects like UV and moisture. This study was made for PVC-wood composites concentrating on thermally treated wood-flour. Colour change, water absorption and mechanical properties were analysed. The results show that both mechanisms, water absorption and UV-degradation must be eliminated as effectively as possible. Thermally treated pine-wood flour inproved dimensional stability and decreased water absorption compared to normal wood flour mixed with PVC.
