Available in thicknesses as thin as 0.0025”, this Teflon and stainless steel composite diaphragm material provides the proven chemical resistance properties of Teflon with an ultra fine stainless steel cloth substrate. This thin-film material displays high tensile strength, resists the creep and cold-flow problems to which ordinary Teflon material are susceptible, and provides the temperature tolerance, chemical resistance, and reliability needed for critical applications. • Temperature Tolerance - 205o C continuous service • Fluoropolymer - 225o C short durations FEP
