Abstract

"MICROFIBRAS POLIMéRICAS PROCESSADAS EM FUSãO, E, PROCESSO PARA PREPARAR UM ARTIGO MICROFIBRILADO". Microfibras e artigos microfibrilados são providos conferindose energia fluida a uma superfície de um filme polimérico processado em fusão, altamente cristalino, altamente orientado. As microfibras e artigos microfibrilados são úteis como suportes de fita, filtros, isolamento térmico e acústico e como fibras de reforço para polímeros ou materiais de construção fundidos, tais que concreto.
