Abstract
<B>PELìCULAS POLIMéRICAS AFINADAS POR ESTICAMENTO, PERMEáVEIS AO VAPOR DE áGUA E RESISTENTES à PENETRAçãO DE SANGUE E VìRUS<D>. Uma película polimérica afinada por esticamento é formada a partir de uma mistura de uma matriz de polímero incluindo um polímero de propileno de baixa cristalinidade tendo não mais do que cerca de 30% de cristalinidade, com um enchimento em partículas. A película afinada por esticamento é permeável ao vapor de água e ainda assim é resistente à penetração de líquidos e vírus. A película pode ser laminada a uma trama não-trançada e é útil em uma ampla variedade de trajes de uso médido e produtos correlatos.
