Abstract

resumo “material microporoso permeável a vapor” descrevem-se materiais microporosos que incluem polímero poliolefínico orgânico termoplástico (por exemplo, poliolefina de ultra alto peso molecular, tal como polietileno), carga particulada (por exemplo, sílica precipitada), e uma rede de poros interligados. os materiais microporosos da presente invenção possuem propriedades de transferência de material volátil controlada. os materiais microporosos podem ter uma densidade de pelo menos 0,8 g/cm3; e uma taxa de transferência de material volátil da superfície de contato com material volátil para a superfície de liberação de vapor do material microporoso de 0,4 a 0,6 mg/(hora*cm2). além disso, quando o material volátil for transferido da superfície de contato com material volátil para a superfície de liberação de vapor, a superfície de liberação de vapor estará substancialmente livre de material volátil em forma líquida.abstract vapor permeable microporous material describes microporous materials that include thermoplastic organic polyolefin polymer (e.g., ultra-high molecular weight polyolefin, such as polyethylene), particulate filler (e.g., precipitated silica), and a pore network interconnected. The microporous materials of the present invention have controlled volatile material transfer properties. microporous materials can have a density of at least 0.8 g/cm3; and a transfer rate of volatile material from the volatile material contact surface to the vapor releasing surface of the microporous material of 0.4 to 0.6 mg/(hour*cm2). furthermore, when the volatile material is transferred from the volatile material contact surface to the vapor releasing surface, the vapor releasing surface will be substantially free of volatile material in liquid form.
