SIGMA® represents the latest generation of biaxially orientated PTFE materials. All components in the SIGMA® range are FDA compliant. The material’s clean nature makes 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.
