The maximum useful proportion of blowing {HEAD ~ agent} in the flowable, foamable gel is also affected by the pressure which is maintained on {TAIL ~ the gel} in the extrusion die passage, being greater when the die pressure is relatively higher under conditions such as when the die orifice is relatively smaller and the through put rate is relatively greater
