The Impact

Abstract Composites of poly(vinyl chloride) (PVC) were prepared with waste, finely ground printing rollers of nitrile rubber over a wide range of composition (up to 90% by weight of rubber component), through melt blending. The effect of different amounts of waste rubber on the tensile strength, % elongation, hardness, and flex crack resistance was studied. There was a considerable increase in the impact properties of PVC. Flex crack resistance was also significantly improved as the specimen did not crack even after 150,000 cycles for all composition containing more than 40% waste rubber. The waste rubber also imparted a plasticizing effect to PVC. The improvement in these properties could be due to interaction between PVC and the acrylonitrile part of nitrile rubber.

The Impact

Abstract The influence of talc and poly (methyl methacrylate) (PMMA)-grafted (g)-talc on the mechanical properties of poly (vinyl chloride) (PVC) was investigated. The graft copolymerization was carried out under nitrogen atmosphere, using the free radical initiation technique. The blend formulations were first dry blended using a mixer before being milled into sheets on a two-roll mill at 165°C, and then hot pressed into composites at 190°C. The flexural modulus of both composites increased with increasing filler content from 0 to 20 part per hundred resin (phr), however the increment of grafted (57.7%) was higher than ungrafted composites (48.5%). A similar trend has also been observed for thermal stability. The impact strength of grafted was increased by 45.82%, whereas 18.96% in reduction was observed for the ungrafted composites. The decrement of flexural strength by 16.6% and 21.1% of grafted and ungrafted, respectively, has also shown the improvement in mechanical properties of grafted composites.
