microFlon® BLUE

Micro-structured PTFE sheets with micro hollow glass spheres

microFlon PTFE gasket sheet, filled with borosilicate hollow glass bubbles, TA-Luft / DVGW certified – FDA compliant

microFlon® BLUE is the new generation of microcellular structured, glass-filled PTFE sealing materials.

The very homogeneous distribution of the micro hollow glass bubbles used gives the material a uniform density, with high adaptability.

The diffusion leakage common with similar gasket types is reduced to a maximum even at low surface pressures.

microFlon® BLUE also shows its strengths at elevated temperatures. Less flow and higher stability lead to secure sealed joints.

This makes microFlon® BLUE the universally applicable PTFE sealing material for all flange connections, even with slightly damaged sealing surfaces, or in stress-sensitive components.

Typical applications
  • Components
    Pipelines, apparatus flanges, also with reduced surface pressures or slight damage
  • Flanges
    Steel flanges, glass, ceramic or plastic flanges, enamelled pipe flanges as well as rubberised flanges
  • Media
    highly aggressive media in the entire pH range, except molten alkali metals and fluorine gas
  • microcellular structured PTFE, inorganically filled
  • High compressibility and adaptability
  • Chemically inert
  • Suitable for high temperatures up to +250 °C
  • Greatly reduced “cold flow
  • Very good recovery behaviour
  • High tightness even with low surface pressure
  • Can be removed without leaving any residue
