High Abrasion Resistance Shoe Sole

Silica used as active reinforcing filler to improve high abrasion resistance in rubber.In this study, the effect of four different silica grades (silica MP BET 161-190, silica powder newsil micro peral, silica 355GR and silica BET higher grade) on the abrasion resistance and other properties of the shoe sole have been studied. The abrasion resistance was determined using DIN 53516 test method and the hardness, specific gravity, tensile strength and elongation at break were determined by following the respective ISO and ASTM standards. The results of the study showed that all four silica grades incorporated shoe soles have achieved acceptable abrasion resistance values. Achieved abrasion resistance value for shoe sole is maximum 350mm3. However silica MP BET 161-190 has 289 mm3 which is also a quite higher abrasion resistance with a minimum loss of rubber in abrasion compared to other three silica grades. Therefore it can be concluded that, silica MP BET 161-190 is better performing as an active reinforcing filler with the highest abrasion resistance and a minimum loss of rubber in abrasion compared to other three silica grades.
