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.
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.
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.
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

|ONE COLOR•••••••••ONE CHOICE
lNERTEX SQ-S is made of 100% virgin PTFE. Our isotropic expansion process completely eliminates the need for binders, fillers. or pigments. This material is engineered to replace all filled PTFE gasket sheet materials in various colors such as fawn, blue, off-white. green, or orange. It will eliminate the "possibility of misuse of these different colored gasket materials. Plus. gasketing inventories will be greatly reduced with INERTEX. SQ-S, the one. all-encompassing gasket material.
lNERTEX SQ-S is so pure that it far exceeds the requirements set forth in the rigid SEMASPEC 92010934B-STD according to testing performed by a SEMATECH recognized laboratory. And, since it does not particulate, lNERTEX SQ-S is the choicefor handling ultra-pure fluids such as ultra-pure water, bio-tech, and pharmaceuticals.
lNERTEX SQ-S is very soft and extremely compressible with relatively light torque. It can be applied in FRP. porcelain, plastic, and glass-lined piping or vessels. Yet, this material is very strong and tough. It can withstand compressive loads of over 40,000 psi without affecting its sealing capability. INERTEX SQ-S is virtually impossible to abuse.
According to the testing done by Ecole Polytechnique Tightness Testing Research Laboratory (TTRL). lNERTEX SQ-S is one of the tightest scaling gasket materials in the world. It can help meet the most strict regulations of the Clean Air Act. Coupled with excellent chemical compatibility with all VOC's, HAP's, and HON's, INERTEX SQ-S becomes the ultimate resolution to the EPA issue.
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
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.
