SQ-S Isotropic Gasket Sheet is manufactured from 100% expanded virgin PTFE by our proprietary Isotropic expansion process. Isotropic expansion provides a highly fibrillated microstructure with nearly equal tensile strength in every direction. This unique structure maximizes performance predictability and stability while minimizing creep and cold flow. According to the testing by Ecole Polytechnique Tightness Testing Research Laboratory (TTRL), Inertex SQ-S is one of the tightest sealing gasket materials in the world.
Suitable for a wide range of pressure and temperature, its chemical compatibility is unsurpassed. It has an unlimited shelf life and will not oxidize or deteriorate like filled PTFE or elastomeric products. Its softness is capable of sealing unfinished surfaces. It allows successful sealing at low values of torque and can be fitted to virtually any shape for easy installation.
