Thermafoil TF-LEX is a low load flexible graphite laminate with excellent blowout and scrubbing resistance. It is a laminated material made with Thermafoil Grade K (TF-K) flexible graphite bonded to both faces of a .005” thick, stainless steel expanded metal insert. TF-K is an industrial gasket grade, monolithic, flexible graphite sheet material containing no binders with an added non-metallic, inorganic, passive oxidation/corrosion inhibitor. TF-LEX requires a much lower seating stress than other graphitic gasket materials and meets most automotive and industrial fluid sealing service requirements. This material will seal a wide variety of liquids and gases over a wide range of temperatures.
