膨体聚四氟乙烯(ePTFE)膜的应用与发展

The Application and Development of Expanded Polytetrafluoroethylene Membrane

膨体聚四氟乙烯(ePTFE)膜是一种具有广泛发展前景的新型绿色环保材料,具有"微纤维—节点"的微观网状结构,最小微孔可达0.1μm,孔隙率高达82%。ePTFE膜具有优秀的防水防尘和透气透湿性能,在服装建筑、防尘滤袋、航天、空气电极、电子照明和包装等领域有着广泛的应用。随着人们对ePTFE膜出色的防水防尘和透气透湿性能的认识加深,ePTFE膜必将在各行各业中产生越来越广泛的应用与发展。

Expanded polytetrafluoroethylene （ePTFE） membrane is a kind of new environmentally friendly material, which has development potential in various fields. It has a microstructure of ＂micro fibre - node＂, and the minimum micropore can be up to 0.1 μm, ana the porosity is as high as 82 %. EPTFE membrane is waterproof, dustproof and breathable, used widely in the fields of clothing, construction, dust filter bag, spacecraft, the air electrode, electronic lighting and packaging, etc. Along with more studies of the ePTFE membrane with excellent waterproof and dustproof and breathable properties, ePTFE membrane will be more and more extensive application and development in various fields.
