Thermoplastic elastomers (TPEs) are polymeric materials, which combine the excellent processability of the thermoplastic materials at high temperatures and a wide range of physical properties of elastomers at service temperature [1]. TPE grades are often characterized by their hardness. Olefinic thermoplastic vulcanizates (O-TPVs) are one of a class of TPE. These materials are composed of vulcanized rubber component in a thermoplastic olefinic matrix. O-TPVs have a continuous thermoplastic phase and a discontinuous vulcanized rubber phase. O- TPVs are dynamically vulcanizated during a melt-mixing process in which vulcanization of rubber polymer takes place. O-TPVs’s principal uses are automotive applications,
appliance uses, building/constructions, prominent electrical uses, business machines and uses in healthcare application [2-3]. Natural rubber (NR) has good resilience, high tensile strength, low compression set, resistance to wear and tear and good electrical properties. For these reasons, NR is usually used for wide range of application. Polypropylene (PP) due to its intrinsic properties such as translucent, good chemical resistance, tough, good fatigue resistance, integral hinge property, good heat resistance. It does not present stress-cracking problems and offers excellent electrical at higher temperatures. These include a lower density, higher softening point (PP doesn’t melt below 160 oC) and higher rigidity and hardness. Easy incorporation of high loading
