Abstract

"MéTODO PARA FORMAR UMA PELìCULA RESPIRáVEL ELáSTICA, PELìCULA RESPIRáVEL ELáSTICA, ARTIGO PARA CUIDADO PESSOAL, CAPA EXTERNA RECREATIVA E VESTIMENTA DE PROTEçãO DESCARTáVEL". Uma película de elastómero termoplástica inclui um elastómero termoplástico e um polímero predominantemente linear semicristalino carregado. A película inclui entre cerca de 25 a 70% em peso de carga, entre cerca de 5 a 30% em peso de polímero linear semicristalino e entre cerca de 15 e 60% em elastómero. A carga é quase associada com o polímero linear semicristalino. A película elástica demonstra um valor de perda de carga em um alongamento a 50% de menos que cerca de 50%, e uma respirabilidade de mais que cerca de 100 9/M¬ 2¬ /24 horas.
