DX Alltra 550ex Expanded PTFE
Alltra 550ex is made in a process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The result material is much softer and more flexible than any other form of PTFE sheet and as a gasket, conforms easily to irregular and rough surfaces. In addition, the material is easier to compress and minimizes creep and cold flow, associated with skived PTFE sheet.
Alltra 550ex 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, and will not contaminate or discolor end products.

Produra® Sheet Gasketing
Produra® sheet gasketing is chemically inert and made from 100% expanded virgin PTFE. It is the ideal sheet for industrial gasketing users who wish to balance sealing reliability with cost. Possessing greater strength than similarly priced PTFE sheets, Produra® sheet gasketing provides better sealing reliability. Mechanically altered to decrease creep relaxation, its fibrous structure is both strong and very conformable to create a tight and lasting seal.
Tensile strength has been identified as a key parameter in relation to a gasket’s ability to resist gross leakage (or blowout) while in service. With higher tensile strength than others in its class, Produra® sheet gasketing is the clear choice for moderate applications.
