Title: THERMOPLASTIC VULCANIZATE COMPOSITIONS
Abstract:
In methods for forming thermoplastic vulcanizates, and thermoplastic vulcanizates formed by such methods, a masterbatch comprising one or more additives in a carrier resin comprising propylene- or ethylene-based copolymer is added to the thermoplastic vulcanizate formulation. The resulting thermoplastic vulcanizate may additionally be passed through a 200 mesh or finer screen and thereafter extruded. The thermoplastic vulcanizates may exhibit increased extrusion throughput rates and enhanced surface smoothness.
