Abstract
Fire and chemical resistant, flexible composites are made from flexible woven, non-woven and knitted substrates and fluoropolymer containing films. Adhesives, such as melt adhesives, may be used in making the composites. The composites are suitable for use in protective garments, and in other articles where flexible chemically resistant materials are needed. A seaming technique for use in protective articles is described.
Claims16
A flexible chemically-resistant protective article having improved barrier properties made from a fluoropolymer laminate composite comprising a flexible fabric substrate and a protective coating lamintaed to at least one side of the said substrate with a melt-bondable fluoropolymer adhesive interlayer, said protective coating having a thickness of less than about 5 mil and comprising a fluoro polymer selected from the group consisting of polytetrafluoroethylene, fluorinated ethylene propylene copolymer, polychlorotrifluoroethylene, copolymers of chlorotrifluoroethylen and tetrafluoroethylene, copolymers of chlorotrifluorethylene and vinylidene fluoride, copolymers of ethylene and tetrafluoroethylene, chlorotrifluoroethylene, perfluoroalkyl vinyl ethers, polyvinylidenefluoride and polyvinylfluoride.
