Abstract

"FILME ELASTOMéRICO RESPIRáVEL FEITO DE COPOLìMERO EM BLOCO DO ESTIRENO". Um filme respirável, elástico incluindo um elastomero de alto desempenho, tal como um copolímero em bloco do estireno, e um elastomero de baixo desempenho, tal como uma poliolefina, enchidos com uma pluralidade de partículas apropriadas para a formação de poros quando o filme é estirado-afilado, o filme tendo sido estirado-afilado, de modo que a porção do elastomero de baixo desempenho do filme forma uma pluralidade de microporos. Também se descrevem empregos para laminados desse filme elástico respirável.
