Sheet mica

Elongated mica discs with rounded ends are protective inserts made of natural muscovite mica designed to shield borosilicate sight glass (DIN 7081) from aggressive media, overheated steam and thermal stress while preserving optical clarity. Positioned between the process medium and the sight glass, they provide thermal and chemical protection and extend the service life of sight glass components.

Product benefits

• Thermal protection for borosilicate sight glass rods and plates (DIN 7081) using natural muscovite mica
• Resistance to high temperatures and aggressive chemical media
• Maintains optical transparency of the sight glass while acting as a protective layer
• Extends operational lifespan of sight glass components in demanding applications

Applications

• Protection of sight glass plates and rods exposed to overheated steam
• Use with liquid process media
• Use with gaseous process media
