Effect of Methocell F50 and Methocell K100 on Molding of PVC Air Soles

The study was conducted with the view of improving the lustiness of the PVC air soles. The formula containing the ingredients; PVC resin, DOP, DBP, R9, Ivamol, MBR did not impart the lustiness on the soles. Hence invention was carried out employing the Methocell F50 and Methocell K100. Interestingly the use of Methocell F50 gave the expected results unlike with Methocell K100. Methocell F50 found to reduce the weight of the soles. It was revealed that the reduction in the weight increased the feasibility of the formulation. Physical evaluations found to give the uniform microcellular polymeric network with the compactness. On the other hand the use of Methocell K100 found to have increased the size of the soles and that was due to probably expanding the microcellular network of the polymeric nature. Due to this Methocell F50 was concluded for the regular manufacturing of the soles with good lustiness.
