Expanded PTFE Sheet Gasket - Gore GR (Sheet Gasketing)
The temperature range of GORE® GR is -268°C(-450°F)to +315°C(600°F), resistant to all media in range pH 0-14 (except molten or dissolved alkali metals and elemental fluorine, particularly at elevated temperature and pressure). Not subject to aging and physiologically harmless within the material’s temperature range, UV-resistant and can be stored indefinitely. Low dielectric constant, insulation resistance, low friction coefficient (μ = 0.02). The maximum applicable pressure as well as the maximum safe operating temperature depend mainly on the equipment. Standard pressures range from full vacuum to 200 bar (3,000 psig).

GORE® GRsheet gasketing has been developed for a secure flange connection offering an enduring seal for all pipeline and apparatus flange connections made of steel. It consists of pure, high quality expanded PTFE (ePTFE) with multidirectional oriented fibril structure that ensures an almost unlimited chemical resistance of the seal.

GORE® GRsheet gasketing is distinguished by its minimum loss of gasket stress (high PQR value according to EN 13555). This is particularly beneficial when gasketing material is subjected to the stress of temperature cycling, high temperatures and external forces, which can lead to leakage and/or blow-out.

The high strength of the material results in increased pressure and blow-out resistance. The higher rigidity of the material simplifies installation of the gasket. GORE® GR sheet gasketing offers a long-lasting seal on an extremely wide range of steel flange geometries.
