Thermoplastic rubber in footwear

Research was carried out in order to improve the image of thermoplastic rubber (TR) as a quality product in footwear in the European Community (EC). Initially, 19 TR compounds were studied. Sole designs were selected appropriate for 3 types of footwear: childrens, sports (basketball and tennis), leisure. Wear trials were subsequently carried out. The effect of the type of injection machine used (screw, screw ram) on the final properties of the TR soles was determined and the effect of the injection variables (speed of injection, TR temperature and cooling time) on the characteristics of the injected soles has examined. Also, the influence of varying mould designs relating to the exterior design (surface pattern) and the interior design (holes) on the final performance of the soles was established.
