microFlon® barite
Microstructured PTFE sheet with barium sulphate
microFlon® PTFE gasket sheet, filled with barium sulphate; TA-Luft certified
microFlon® barite is a sintered PTFE gasket with highly resistant filler, mainly for applications in the chemical industry.
Finely dispersed barium sulphate gives microFlon® barite improved cold flow resistance and good relaxation properties.
Due to the high chemical resistance of the filler, microFlon® barite can be used in contact with a variety of aggressive media.
Typical applications
- Components
Piping systems, apparatus flanges - Flanges
Steel flanges or other metallic flange systems - Media
Strong alkalis, weak acids, chlorine, common media in chemical and petrochemical applications
