INNOVATIVE.TOTAL FREEDOMCutting-Edge Material TechnologyFROM OXIDATIONEver since inventing the spiral wound gasket nearly a century ago,Flexitallic has been at the forefront of fluid sealing innovation.In 1999, Flexitallic set new standards for sealing technology with theintroduction of Thermiculite Critical Service Grade gasket materialavailable in Tanged Sheet—and later in Spiral Wound Filler andFlexpro (kammprofile) styles.Conventional graphite gaskets are susceptible to attack by oxidizingagents. This occurs from oxygen flowing through pipes, or simplyfrom oxygen present in the atmosphere surrounding the flange. Therate at which graphite oxidizes depends on the applicationtemperature and the concentration of oxygen present. But when itdoes happen—the end result is seal failure.Exclusive to Flexitallic, this revolutionary material, comprised ofchemically and thermally exfoliated vermiculite*, simulated thestructure of exfoliated graphite, with one notable exception—itmaintained integrity through a wide range of extreme temperatures.The unique composition of Thermiculite gasket material ensures thatseals maintain their integrity at maximum service temperatures farexceeding that of graphite.All Thermiculite Critical Service Grade products were designed andengineered for high temperature processes rated for service up to980 C (1800 F).There really is no comparison. When it comes to worry-free sealing,choose Thermiculite Critical Service Grade or Thermiculite Performance Grade and eliminate the risk of oxidation altogether* Vermiculite is a naturally occurring mineral with a plate-like structure demonstratingan exceptionally broad range of chemical and temperature resistance.VERSATILE.A New Level of PerformanceThrough our continued dedication to research and development,Flexitallic is now proud to offer our customers a new series ofThermiculite products.New Thermiculite Performance Grade gasket material—developedfor use in more moderate temperature applications—maintains thesame broad chemical resistance and freedom from oxidation that hasmade Thermiculite Critical Service Grade such a success.This innovative and versatile material is available in CalenderedSheet and Spiral Wound Filler styles, and is suitable for replacingaramid fixer, glass fiber, carbon fiber, PTFE and graphite in a widearray of applications.COMPLETE.The Total Static Sealing SolutionSince its inception, Thermiculite gasket material has proven itself asan effective long-term sealing solution in over 1000 of the mostdemanding industrial sealing applications—the most complete rangesince asbestos.With the combination of Thermiculite Critical Service Grade (800series) and Thermiculite Performance Grade (700 series), a single,proven material can be used for virtually all of your sealingrequirements. That's why we call Thermiculite The Total StaticSealing Solution.The Tightness Testing Research Laboratory (TTRL) at École Polytechnique inMontreal on behalf of the Pressure Vessel Research Council (PVRC) performedindependent testing to show that the maximum service temperature for graphite inlong-term service is much lower than that quoted in manufacturers' literature. Thistable summarizes those results.* Maximum service temperature results based on style 735.
