Round mica discs

Product catalog summary

Introduction
Mica discs are used as heat protection for borosilicate glass sight plates according to DIN 7080. They are particularly effective in environments with aggressive media, superheated steam, or high temperatures, extending the service life of the glass.

Specifications
Mica discs are made from natural muscovite mica, known for its high temperature and chemical resistance. They can withstand operating temperatures up to 320 °C when used with MAXOS® borosilicate glass. The discs are available in various diameters ranging from 42 mm to 250 mm, with a thickness of 0.15 - 0.20 mm.

Operating Conditions
The discs provide reliable protection under extreme thermal and chemical conditions, acting as a barrier against aggressive media. This reduces maintenance costs and downtime. They ensure even pressure distribution, enhancing mechanical stability, and are suitable for use in chemical, pharmaceutical, and food industries, as well as power plants.

Technical Information
Mica discs have a coefficient of expansion between 90 x 10–7 and 135 x 10–7 K–¹, an elasticity modulus of 180 x 10-³ to 170 x 10-³ N/mm², and thermal conductivity ranging from 0.25 to 1.7 W/(m·K). They are resistant to radiation, organic solvents, acids (except hydrofluoric acid), and oils.

Quality and Customization
Quality inspections ensure narrow tolerances and excellent properties. Custom designs are possible, with diameters up to 400 mm.

Conclusion
Mica discs are a critical component for protecting sight glass plates in high-temperature and chemically aggressive environments, offering durability and reducing operational costs.

Round mica discsRound mica discs made of muscovite natural mica USAGE Mica discs for borosilicate glass according to DIN 7080 as reliable heat protection and to ensure functionality Mica discs are an effective accessory for sight glass plates made of borosilicate glass according to DIN 7080. They serve as heat protection and a protective layer between the process medium and the glass surface, especially in applications with aggressive media, superheated steam, or high temperatures. In connection with MAXOS® borosilicate glass plates according to DIN 7080, operating temperatures of up to 320 °C are achievable. The mica discs significantly extend the service life of the sight glass plates. The principle of operation is based on the high temperature and chemical resistance of natural muscovite mica. The mica disc is positioned between the process medium and the sight glass without significantly impairing optical transparency. This prevents the borosilicate glass from being damaged by erosive or corrosive media as well as by thermal shocks. 1) Special dimensions possible Operating conditions: Through production and quality inspections during the process, the property values of the Mica discs and the narrow tolerances are guaranteed. With these excellent properties, Mica discs can be used as an additional safety version for sight glass plates under extreme conditions. The Mica discs provide reliable protection particularly under high thermal and chemical loads. They act as a barrier against aggressive media, extend the lifespan of the underlying sight glass plates, and thus reduce maintenance costs and downtime of systems. Moreover, the precise processing ensures an even pressure distribution on the sight glass, which additionally increases mechanical stability. The flexible application possibilities of the ACI-Mica discs make them an ideal complement for safety-critical applications in the chemical, pharmaceutical, and food industries, as well as in power plants and facilities with high-temperature processes. 17092025 - Subject to technical changes and errors!
