Processo para formar uma película respirável elástica e película respirável elástica formada por este processo

摘要

A thermoplastic elastomer film includes a thermoplastic elastomer and a filled semi crystalline predominantly linear polymer. The film includes between about 25 and 70 weight percent filler, between about 5 and 30 by weight percent semi-crystalline linear polymer, and between about 15 and 60 by weight elastomer. The filler is closely associated with the semi-crystalline linear polymer. The elastic film demonstrates a load loss value at a 50 percent elongation of less than about 50 percent, and a breathability of greater than about 100 g/m²/24 hours.
