Abstract : Thermoplastic rubber molding compounds were investigated to determine the feasibility of using this material for certain configurations. Thermoplastic rubber can be processed directly into finished products, using standard thermoplastic molding and extruding equipment. Three series of material, all from the same manufacturer, were evaluated. The mold shrink factors, molding conditions, and possible applications for each series were evaluated. Molding parameters were established, and a relationship of these parameters to mold shrinkage was determined. The results indicated that the shrink factor depended on the series of material more than on the molding conditions. It was concluded that thermoplastic rubber can be easily processed in conventional thermoplastic equipment.
