Fragrant Rubber Sole with New Formulation Employing EVA Crump

The invention provides improvement over the entire physical properties of rubber soles like tensile strength, modulus strength, shore A. Oil 205 and 541 have a very good lubricating effect on their microcellular structure, breakability and resilience. An aroma was introduced to mask the rubber smell and the shore A was further investigated employing the naphthenic oil that was added in higher and lower dosages in the formulations. The cost factor of the soles was bit high that compare to other oils like 205 and 541. Their physical evaluation at FDDI was found to be compatible from customers’ point of view. Tensile strength was from 104-146 Kg/cm2 and the elongation was 680-850%. Hardness shore A was from 33-68 and volume loss was from 190-265%.
