Wood plastic composites prepared from poly(vinyl chloride) and Balau sawdust (Shorea obtusa): Mechanical properties and N-(β-aminoethyl)-γ-aminopropyl trimethoxysilane compatibilization

摘要

Wood plastic composites (WPC) prepared from poly(vinyl chloride) (PVC) and Balau wood particles were studied in the current research. Various particles sizes of wood flour with a top cut of 45, 75, 106, 180 and 250 μm was investigated at the range of 0-80 phr. Experimental results indicated that WPC was more stiff and brittle when the Balau wood flour was applied at all compositions. There was no statistically significant difference in the tensile strength and the elongation at break among the composites with different particle sizes. Treating the composites with silane coupling agent induced increments in both the impact strength and the tensile elongation at break.
