lNERTEX SQ-S GASKET SHEET is the world's first 100% expanded PTFE in a true 60" x 60" format. This material is manufactured by our proprietary isotropic-expansion process which breaks all the rules traditional to gasket material manufacturing of the past. 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. lNERTEX SQ-S definitly is an all-purpose gasket sheet that is setting the new standard in gasket technology.

USER-Friendly
lNERTEX SQ-S has an unlimited shelf life and will not become brittle, age, or otherwise deteriorate in the application. This material is unaffected by UV. ozone, and corona. It is easily hand or die cut. And, when necessary, lNERTEX SQ-S can be removed easily from flange surfaces due to the non-sticking nature of PTFE.

QUALITY ASSURANCE
lNERTEX SQ-S is manufactured in our ISO 9002 certified facility (Certification *94/4207). To assure receiving lNERTEX SQ-S in the best condition each and every time, all sheets are individually rolled onto a paper tube and shrink-wrapped before being put into a blister sleeve and sturdy box.

THE FAMILY
INERTEX family represents a full line of 100% expanded PTFE
gasketing and packing. Other products of INERTEX are as follows:
• INERTEX UHF Joint Sealant
• lNERTEX UHF Gasket Tape
• lNERTEX EZ Seal Insertable Gaskets
• INERTEX Valve Stem Packing
Custom designed products are also available upon request

General Information
INERTEX UHF Joint Sealant, UHF EZ Seal lnsertable Gaskets, and SQ-S sheet gasketing
material are expanded PTFE (Teflon) products made from 100% virgin PTFE
(Polytetrafluoroethylene). INERTEX products are produced via a unique process. protected
under U.S. patent #5,098.625 (see patent within booklet).

Our UHF process generates a Uniformly and Highly Fibrillated microstructure. This high
ratio of the fibrillation results in millions of interlocking fibrils which provides significantly LESS
CREEP and COLD FLOW characteristics than other expanded PTFE products. INERTEX
products are more dense, are more easily compressed with less clamping force, and fill flange
surface irregularities more easily than other gasketing products.

Under compression INERTEX products form an extremely strong inner structure which
translates into high retention of bolt load with a tighter sealing gasket. This provides the user
with lower emissions at every gasketed joint.

Because it is a formed in-place gasket, INERTEX UHF Joint Sealant is ideally suited for large
diameter applications such as pressure vessels, tank lids, heat exchangers, manholes, and
can also be used to form gaskets for any irregularly shaped equipment configuration.

INERTEX· UHF EZ Seal lnsertable Gaskets are preformed rigid insertable gaskets which fit all
standard ANSI Flanges 150# and 300# class. All properties and information defined in the
following data for INERTEX UHF Joint Sealant are applicable to INERTEX UHF EZ Seal
Insertable Gaskets.

INERTEX SQ-S Sheet Gasket material is the largest expanded PTFE sheet in the world at 77"
x 77" in either 1/16' or 1/8" thickness. It is easily hand cut or die cut. Please refer to the
separate test data section for standard ASTM testing results.

Due to the characteristics of 100% Virgin PTFE, all INERTEX products are completely
unaffected by all common chemicals, do not deteriorate with age. wiU not contaminate flow
media and will not leave a residue on the sealing surface when removed.
