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
