摘要：

Gum and filled compounds of styrene-butadiene rubber are extruded through a laboratory extruder by varying the feeding rate at different temperatures and screw speed (rpm). The extruded compounds are vulcanized up-to their optimum cure times and the mechanical properties of the vulcanizates are determined. From the properties data obtained it is concluded that there is a specific feeding rate within the starved fed region, which results in maximum improved mechanical properties. The enhancement in properties is found to be due to Better thermal and shear homogeneity.
