METHODS OF MAKING THERMOPLASTIC VULCANIZATES (TPV)

摘要

Methods of making thermoplastic vulcanizate are provided, including the steps of (a) extruding an elastomeric component and a thermoplastic polymer component to form a dynamically vulcanized me (b) passing the dynamically vulcanized melt into a vessel, comprising two intermeshing, counter-rotating twin screws, to produce a uniform dynamically vulcanized me and (c) filtering the uniform dynamically vulcanized melt and recovering a thermoplastic vulcanizate.
