Water resistance and thermal stability of hybrid lignocellulosic filler–PVC composites

摘要: In this study, composites based on polyvinyl chloride (PVC), pulp fiber (PF), and wood flour (WF) were made by injection molding. The effects of two variable factors, namely the filler form loading level, composite physical properties examined. result clearly showed that major part water absorption was due to PF. It found in lignocellulosic material base is significantly higher than neat PVC. Besides, increased sharply with increasing cellulosic loadings composites. case hybrid composites, rate uptake correlated percentage weight WF, lower WF (higher PF) exhibit absorption. onset degradation temperature indicates improved thermal stability samples. other words, illustrates property increases after using PF further addition WF.
