Effect of Calcium Sulfate Whisker on the Mechanical Properties of PVC

Wei LI, Shu-lin YE, Rui HUA, Kai-yuan CHEN


In this study, mechanical properties tests were performed on 0, 5, 10, 15, 20 and 25 wt% calcium sulfate whisker (CSW) filled on poly(vinyl chloride) (PVC) (blended by single screw extruder) to identify the effect of CSW weight fraction on the mechanical properties of PVC. The introduction of calcium sulfate whisker in PVC not only reduced the cost of PVC composites, but also improved the overall performance of PVC. The binary blends were first characterized in terms of mechanical properties. The properties of subsequent CSW/PVC blends were investigated through SEM.
Results show that the introduction of CSW has improved the impact strength, tensile modulus and tensile strength of the CSW/PVC composites to some extent.
