PTFE Products

For industries demanding reliability in extreme conditions

Developed for processes ranging from cryogenic temperatures to 260ºC, and suitable for sealing virtually every chemical medium across the entire pH range (0-14). Flexitallic Sigma® PTFE materials contain non-stick properties that aid in an easy removal process after their usage to dramatically reduce the downtime on shutdown.

All components in the Sigma® range are FDA compliant. The material’s clean nature make it ideal for use where product contamination is of concern, such as food, pharmaceuticals and electronics.

The chemical resistance and dimensional stability of the material ensures total sealing reliability and minimises fugitive emissions.

We also offer expanded PTFE products (ePTFE) sheet sealing material and Gasket Tape.
