Molding of PVC Air Soles with Modified Formulation

Molding of PVC Air soles are currently produced with the formulations of Resin (25 Kg), DOP/DBP ( 8+8 Kg), CPW (3 Kg), R9 (0.750 Kg), Ivamol (0.500 Kg), Stearic acid (0.500 Kg), Foaming ADC (0.350 Kg), MBR (8kg) and CaCO3). Quality parameters investigated for such products have shown that internal microcellular structures were not uniform and durability was also weak. Hence the invention was undertaken eliminating CPW and Stearic acid. Instead of this Naphthenic oil was employed for molding the soles. Quality evaluations have shown the internal microcellular structures were quite uniform and had great impact on durability. The formulation was also found to be feasible for the regular production. High resolution pictures of the soles have exhibited the uniform polymeric network.
