SIGMA® Gaskets by Flexitallic
Utilising a unique manufacturing process exclusive to Flexitallic, we created SIGMA®, an innovatively-engineered line of biaxially-orientated PTFE gasket materials. Developed for processes ranging from cryogenic temperatures to 500F (260C), and suitable for sealing virtually every chemical medium across the entire pH range (0-14), SIGMA® pairs the outstanding chemical resistance of PTFE with enhanced dimensional stability to improve overall material stress retention. The non-stick properties of the SIGMA® range of materials offer excellent removal after usage to dramatically reduce the downtime on shutdown. In addition, all components in the SIGMA® range are FDA compliant. This inherently clean nature makes them ideal for use in industries where product contamination is of concern such as food, pharmaceuticals and electronics.
