Mica

Round mica discs are protection discs made of natural muscovite mica for sight glass plates (borosilicate glass). They provide heat and chemical protection between the process medium and the glass while preserving optical transparency and extending the service life of sight glass plates.

Key product information

• Purpose: Heat protection and protective intermediate layer for sight glass plates to shield against chemical effects, overheated steam and thermal shocks.
• Material: Natural muscovite mica (muscovite).
• Standard / compatibility: Designed for borosilicate glass according to DIN 7080; compatible with MAXOS® borosilicate glass discs.
• Maximum operating temperature (with MAXOS® borosilicate glass): up to 320 °C.

Applications

• For liquid process media.
• For gaseous media (overheated steam, process gases).
• Where protection is required against aggressive, erosive or corrosive media.

Benefits

• Reliable heat protection for sight glass plates.
• Significantly extends service life of borosilicate sight glass.
