The INERTEX family of gasketing and sealing products are produced by proprietary processes protected by both u.s. and world. All INERTEX products share the following typical properties:
• 100% expanded virgin PTFE • Pressure range, full vacuum to 3,000psi • Low coefficient of friction (.02 like wet ice)
• Temperature range, -450°F to +600°F • Extremely soft, excellent conformability • FDA suitable (FDA 21 CRF 177.1550)
• pH range from 0 to 14 • Little creep or cold flow • No aging or hardening in service

Why use Inertex SQ-S Huge Sheet?
The photo to the left shows just one of the reasons....
Here is a 73" cut Inertex SQ-S Huge Sheet that was used successfully in a 3600 square foot spiral heat exchanger used as a foul condensate pre-heater running at 332F with 150psi pressure. Product replaced a welded Gylon filled PTFE sheet. Why Inertex SQ-S Huge Sheet? Conformability, a one-piece gasket without the hard weld points, temperature resistance, ease of cutting (trimming,) and cost.

The INERTEX® family of gasket sheets are produced by a proprietary expansion process which generates a highly fibrillated microstructure with nearly equal tensile strength in every direction (ISOTROPIC.) This unique structure maximizes performance predictability and stability while minimizing creep and cold flow. Whatever your application, INERTEX® SQ-S Sheet Gasketing is setting the new standard in providing the user with the tightest, most leak-free gasket possible.
