The properties of PVC resin grains have been shown to influence the bulk density and flow properties of PVC resins and powder compounds. Bulk densities of PVC resins and powder compounds are highly dependent on grain shape. Lower bulk density has been related to more irregular grain shape. Flow properties of PVC resins and powder compounds improve with increased grain size. Twin screw extrusion rates are directly proportional to the compound bulk density in the feed throat.
