TECHNICAL DATA INFORMATION
for
INERTEXÒ UHF JOINT SEALANT
INERTEXÒ EZ SEALS INSERTABLE GASKETS
INERTEXÒ SQ-S GASKET SHEET
General Information
INERTEXÒ UHF Joint Sealant, UHF EZ Seal Insertable Gaskets, and SQ-S sheet gasketing
material are expanded PTFE (Teflon) products made from 100% virgin PTFE
(Polytetrafluoroethylene).
INERTEXÒ 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.
INERTEXÒ
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
INERTEXÒ 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,
INERTEXÒ 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.
INERTEXÒ UHF EZ Seal Insertable 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
INERTEXÒ UHF Joint Sealant are applicable to
INERTEXÒ UHF EZ Seal
Insertable Gaskets.
INERTEXÒ 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 INERTEXÒ products are completely
unaffected by all common chemicals, do not deteriorate with age, will not contaminate flow
media and will not leave a residue on the sealing surface when removed.
