DatasheetmicroFlon BLUE

microFlon PTFE Gasket Sheet with hollow glass microspheres - TA-Luft / DVGW certified - FDA conforming


microFlon® BLUE is the new generation of  microstructured, reinforced PTFE gasketing materials.

Due to the very homogenous distribution of hollow glass microspheres, microFlon® BLUE gets its uniform density and a high adaptability.

It assimilates to flange roughness and unevenness, applying just low gasket stress, and reduces surface diffusion to the minimum.

Even at increased temperatures microFlon® BLUE shows its advantages. Low compressive creep and high stableness lead to a reliable jointing.

With this microFlon® BLUE is the optimum PTFE gasketing for all flanges with slightly damaged surfaces, distorted flanges, or fragile components.

Typical Applications

piping systems, apparatus flanges, also with reduced gasket stress or damaged surface

steel, metal alloy, glass, ceramics or plastics flanges, glass lined and rubber lined piping systems

highly aggressive media, except for molten alkali metals and fluorine gas.
