Expanded PTFE Gasket Sheets
ePTFE- Gasket Sheet is a technologically advanced gasketing material providing all advantages of PTFE in a pure expanded form that resists cold flow, Flexible and economical, it is fast, easy to cut and install. These are supplied as pre-cut gaskets or in sheet form to cut on site as required.
Because of its multidirectional fibrous texture, ePTFE – Gasket Sheets show very good material characteristics at high surface pressures and increasing temperatures. Even under extreme operating conditions there are very low changes in width and in height, compared to other PTFE materials. By using gaskets made of ePTFE SHEETS high surface pressures will be maintained also at high temperatures.
ePTFE – Gasket Sheets is especially designed for highest safety requirements and for the application in critical joints such as flanges in oxygen pipelines.
For various applications the ePTFE – Gasket Sheets are available in diverse dimensions, heights and densities.
EPTFE (Expanded PTFE) is a Universal Expanded PTFE Sheeting sheet gasket material for most services. Seals rough and irregular surfaces. Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness. Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed. Chemically resistant over the Q-14 pH range. Specific gravity: 4 to 6. Suitable for temperatures to 315 °c.
CONSTRUCTION EPTFE
gasket sheet is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than conventional PTFE sheet. EPTFE is much softer and more flexible than regular PTFE sheet and thus conforms easily to irregular and rough surfaces. In addition, the material is easier to compress and minimizes creep and cold flow.
APPLICATION / SERVICE
EPTFE is an all purpose gasket sheet that can replace all other types of PTFE sheet. It will seal all aggressive chemicals over the entire 0-14 pH range except for molten alkali metals and elemental fluorine. Made from 100% virgin PTFE, EPTFE not only resists chemical attack, but it will not contaminate or discolor end products. These industries currently use expanded PTFE sheet:
• Distilleries • Food and Beverage
• General Chemical • Marine
• Iron and Steel Manufacturing • Pharmaceutical
• Petrochemical • Pulp and paper
• Power generation
