A Study of Polyvinyl Chloride Modified by Barium Sulfate

Abstract:

PVC/BaSO₄ composites were prepared by melt blending method. The mechanical properties, microstructure and thermal stability of the composites were investigated. The results indicated that BaSO₄ decreased the tensile yield stress and improved the elongation at break of PVC composites. Ductile fracture characteristics such were observed in the tensile fracture surface of PVC/BaSO₄ composites. The toughening mechanism was cavitations toughening mechanism and shear zone toughening mechanism. The reaction of dehydrochlorination was limited by the addition of BaSO₄.
