If you’re in search of a gasket material that offers unparalleled chemical resistance, exceptional conformability, temperature resistance, and tensile strength, look no further than Gore GR® Expanded PTFE Gasket Sheet.
This high-quality grade of expanded PTFE sheet is a game-changer in the world of gasketing, combining unique properties that set it apart from conventional PTFE sheets.
In this post we explain just what Gore GR ePTFE is, the benefits it provides, common applications and information on how we can supply it to suit your needs.
Unmatched Chemical Resistance and Conformability
Gore GR is manufactured from 100% expanded PTFE and contains no binders, fillers, or additives.
Thanks to this exceptional construction, it provides significantly less creep and cold flow compared to traditional PTFE sheets.
The material’s softness allows it to conform to rough sealing surfaces, while its compressibility transforms it into an incredibly tough gasket that forms a tight, effective, and long-lasting seal.
For more in-depth information on creep, chemical resistance and other attributes, we suggest consulting our Gore GR Technical Data Sheet.
If the information you require isn’t there, please do reach out to your local Associated Gaskets branch. We’ve been working with this material for decades across numerous industries and are ready to provide any assistance we can.
Are Gore-Tex and Gore GR the same thing?
Sort of.
Gore-Tex® is a name used by W.L. Gore for a range of their products. One of those used to be their ePTFE gasket sheet.
In the years since, their range has expanded to include a variety of filter materials, clothing and more.
They now refer to their high performance gasket sheet as Gore GR.
Versatile and Reliable
Gore GR gaskets have proven their mettle in a wide range of applications, sealing pressures ranging from vacuum to 200 BAR.
Its remarkable resistance to all media within the pH 0-14 range, except molten alkali metals and elemental fluorine, makes it ideal for environments with aggressive chemicals.
Furthermore, Gore GR excels in temperatures ranging from -268ºC to 315ºC, making it a top choice for applications in extreme conditions.
Tailored Solutions for Your Needs
At AG, we offer Gore GR in standard thicknesses of 1mm, 1.6mm, 3.2mm, and 6.4mm, with other sizes available upon special request.
Whether you need the material in sheet or cut gasket form, we can produce gaskets to fit all types of standard or non-standard flanges based on standard dimensions or your specific dimension lists, sketches, drawings, or samples.
Our comprehensive fabrication capabilities and large stock holdings ensure we can produce premium ePTFE gaskets made from Gore GR to meet any industrial requirement.
Gore GR Gasket Sheet Applications
GORE GR Sheet Gasketing is a tough, dimensionally-stable and chemical-resistant gasket sheet for sealing steel pipe and equipment flanges in a wide range of applications and process conditions. It reliably seals flanges with rough surfaces, and is ideal for flanges that require complex gasketing shapes or larger gasketing sizes.
