Sigma^® pairs the outstanding chemical resistance of PTFE with enhanced dimensional stability. Developed for processes ranging from cryogenic temperatures to 260°C and suitable for sealing virtually every chemical medium across the entire pH range (0-14).

The Sigma^® range of 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.
