Specificationsptfe teflon gasket seal GINSEAL PTFE -based gasket materials are able to withstand significantly more aggressive chemical environments (including highly oxidizing environments) than standard non-asbestos gasket materials. However their temperature, pressure and mechanical performance are inferior to standard non-asbestos gasket materials. Metal inserted and expanded PTFE are able to operate at higher pressuresExpanded PTFE GasketItem No.: JSG-PT20Die-cut gasket made from multi-directional stretched expanded PTFEGasket thickness: 1; 1.5; 2; 3; 4, 5; 6 mm other thicknesses is availablePressure: 40 barsTemperature: -200 ° C to 225 ° CUse: Steel flange, steel container, enamel flange, enamel container,Glass flange, heat exchanger
