ABSTRACT = {In search of improved materials for efficient shock and vibration mounts for machineries,
graphite loaded NBR and NBR/PVC blend were made and investigated. The scorch time was
seen to be reduced and vulcanization rate was enhanced due to graphite inclusion. Scanning
electron microscopy images have shown homogenous dispersion of graphite powder. NBRgraphite showed a gradual increase in the hardness, tensile strength, Young’s modulus, and
tear values with increasing graphite loading. In the case of NBR/PVC-graphite composition, a
drop in the tensile strength and increase in the Young’ modulus and tear strength was observed.
Various mathematical models were used to investigate hardness-Young’s modulus relationship
and correlation of the modulus with aspect ratio and volume fraction of graphite established.
Different equations were also used to predict effect of graphite particle shape factor and
hardness of the vulcanised composition on compressive modulus and compared with measured
Young’s modulus.},
