PTFE SheetFluorocarbon resins are a group of high performance engineered plastic resins featuring high crystallinity and high molecular weight. Outstanding resistance to chemicals is one of the primary benefits. PTFE has excellent resistance to 98% of the commercially used chemical compounds.
A broad temperature range of -450ºF to +500ºF make this gasket material suitable for most of the conditions found in industry. Water absorption of PTFE is negligible, less then 0.01% by ASTM test. And, it is FDA-approved for food contact.
Properties of Pure PTFE
Filled PTFETo address the problem of cold flow of PTFE, it is now available with a filler that helps prevent this cold flow. Usually filled with a form of silica, this product is known by many names: TopChem (Thermoseal), Gore-Tex GR (W. L. Gore), Gylon (Garlock, Inc.) and Sigma (Flexitallic) to name a few. Generically it is called "glass-filled PTFE".
While retaining the temperature and chemical resistance properties of pure PTFE, this product cold flows less because of the glass fiber filler. The trade-off is in sealability, as some of these products require considerable stress to effect a seal.
Durlon Modified PTFE Sheet
|Durlon 9000 and 9000N|
|Durlon 9000 (blue) and 9000N (neutral) are designed for use in process piping and equipment in chemical, pulp & paper, pharmaceutical, oxygen & industrial gases, food & beverage and other general industrial applications. These gasket sheets are excellent choices where physical properties such as non-contamination and resistance to highly aggressive chemicals are required.||Durlon 9000 has been tested, approved and used for chlorine and caustics services. Unlike generic skived PTFE, the various shapes of fillers in Durlon 9000 are homogeneously blended with pure PTFE resins and do not wick or cause corrosion on flange faces. Also, independent testing has shown the fillers in Durlon 9000 to be more evenly dispersed than filled PTFE with layered construction. Therefore, it has more consistent physical and mechanical properties and does not have voids, separation and chemical compatibility problems found in layered PTFE.|
Versatile and Reliable Seal
Durlon PTFE Sheet
|Durlon 9200W is a barium sulfate filled PTFE designed for use in piping and equipment in chemical, pulp & paper and associated industries where resistance to aggressive chemicals and excellent sealability is required. Due to our unique and innovative manufacturing process, 9200W has outperformed all layered filled PTFE materials proving to be more resistant to the "popcorning" effects of aggressive monomers such as styrene, methyl methacrylate and butyl acetate.|
Versatile and Reliable Seal
|Durlon 9600 is an expanded PTFE gasket material designed to seal at low loads and resist creep and cold flow while being able to withstand high flange load and high pressures.|
Durlon 9600 will easily conform to irregular surfaces that may be warped, etched, pitted or tool marked. These characteristics make Durlon 9600 your best choice for a broad range of aggressive chemicals where plastic flanges and / or low bolt loads are a requirement.

|The patented Inertex UHF (Uniformly and Highly Fibrillated) Process improves upon existing expanded PTFE products. Inertex is a more dense and highly fibrillated form of expanded PTFE. It provides the user with even less creep relaxation and cold flow than existing expanded PTFE products. Inertex is 100% virgin PTFE with no fillers or binders and provides all of the spectacular properties and benefits of PTFE.||The unique properties created by the Inertex UHF process makes Inertex the most effective and versatile material in its class. Inertex easily conforms to damaged or pitted flange surfaces. It also requires a low compressive load to seal which makes it an excellent material for FRP and glass lined flanges. Its low coefficient of friction of 0.2 (like wet ice) means gaskets are easily removed.|
|INERTEX 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 isometric-expansion process which breaks all the rules traditional to gasket material manufacturing of the past. Isometric-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. INERTEX SQ-S definitely is an all-purpose gasket sheet that is setting the new standard in gasket technology.||
One Color.....One ChoiceINERTEX SQ-S is made of 100% virgin PTFE. Our isometric-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.
Pure.....IntegralINERTEX 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, INERTEX SQ-S is the choice for handling ultra-pure fluids such as ultra-pure water, bio-tech and pharmaceuticals.
Soft..... but StrongINERTEX 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 the one virtually impossible to abuse.
The TightestAccording to the testing done by Ecole Polytechnique Tightness Testing Researchy Laboratory (TTRL), INERTEX SQ-S is one of the tightest sealing 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.
User-FriendlyINERTEX 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, INERTEX SQ-S can be removed easily from flange surfaces due to the non-sticking nature of PTFE.

|INERTEX UHF Joint Sealant looks and feels different from other Joint Sealant products. It is smooth and flexible with an exceptionally uniform texture and density. Under the surface is a microscopic structure that makes this remarkable material the strongest, most versatile sealant available today. INERTEX UHF Joint Sealant is made of 100% virgin PTFE.||INERTEX alone uses a patented process that produces a uniform and highly fibrillated microstructure with thousands of small fibers running in many directions. These create a soft and pliable, yet very tough oval-shaped joint sealant that is very compressible with a high tensile strength. INERTEX UHF Joint Sealant provides excellent cold flow and creep relaxation resistance. It is FDA suitable and it comes with an easy peel-off self-adhesive backing that makes installation simple.|

Lasts Longer, Saves Time, Cost and is Very Versatile
|INERTEX EZ-Seal Gaskets are designed with two things in mind; ease of installation and maximum performance. The raised inner portion of the EZ-Seal is manufactured to compress easily during installation. This allows it to fill in any irregularities, voids and nicks, even on wire drawn flanges. EZ-Seal Gaskets require less bolting stress to seal than conventional PTFE envelope gaskets, plain PTFE gaskets or any filled PTFE products on the market today.||This feature makes EZ-Seal Gaskets the absolute best choice for glass lined or plastic flanges. EZ-Seal Gaskets can be used with all ANSI raised face flanges. EZ-Seal Gaskets are easy to install in tight situations where only minimal separation of flanges can be accomplished. Once installed, EZ-Seal Gaskets provide a long and dependable service life because they are made from 100% pure expanded PTFE. They will not age, harden, shrink or dry out in service.|
Lasts Longer, Saves Time and Cost100% expanded PTFE lasts much longer than any other gasket material. When changing gaskets, INERTEX EZ-Seal Gaskets will not stick to surfaces and can be easily removed. The EZ-Seal Gasket comes in a sturdy protective package that protects the gasket from damage until needed.
