Blending resins are well known by plastisol compounders as an economical substitute for PVC dispersion resin and as viscosity modifier. As dispersion resin supply tightens, interest grows in blending resins and how to choose the one that best fits the compounder's specifications. Eleven representative blending resins have been characterized, compounded into plastisols and screened for performance. A regression analysis and resulting contour plots have supplied a means of correlating resin molecular weight, particle size and surface area with plastisol, gel/fusion, and physical properties. The trends described in the contour plots allow the prediction of the best blending resin criteria for a specific application.
