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

INERTEX® SQ-S Gasket Sheet
is the world's first 100% Expanded PTFE sheet in a true 60"x60" format, and now is also available in 77"x77" size (SQ-S "H" Huge Sheet.) Independent laboratory tests have revealed that SQ-S is one of the tightest gasket materials available to the market.

The INERTEX® SQ-S "V" Rigid Gasket Sheet brings an improved rigidity to the SQ-S Gasket Sheet while maintaining the excellent sealing characteristics of SQ-S. It is designed for difficult installation conditions when rigidity is an important factor.

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.
