Process of forming a dynamically vulcanized thermoplastic elastomer film, also referred to as DVA film, directly from a DVA raw material, the process comprising the steps of forming a thermoplastic elastomeric material melt comprising an elastomer and a thermoplastic resin in a first mixer under conditions such that the thermoplastic elastomeric material is dynamically vulcanized, passing the thermoplastic elastomeric material melt formed in the first mixer through a second mixer to form a uniformed melt, and passing the thermoplastic elastomeric material melt exiting from the second mixer through a film die to form a thermoplastic elastomer material film. |
