Product catalog summary
Overview: Mica discs are used as heat protection for borosilicate glass rods according to DIN 7081. They protect against aggressive media, superheated steam, and high temperatures, extending the service life of sight glass plates.
Specifications: Mica discs are made from natural muscovite mica, known for its high temperature and chemical resistance. They can withstand temperatures up to 500°C, with a maximum allowable temperature of 320°C when used with MAXOS® borosilicate glass. The discs are available in various dimensions, with thicknesses ranging from 0.15 to 0.20 mm.
Operating Conditions: Mica discs are suitable for extreme conditions, providing reliable protection under high thermal and chemical loads. They are used in safety-critical applications across industries such as chemical, pharmaceutical, food, and power plants.
Technical Information: The discs have an expansion coefficient of 90 x 10–7 K–¹, an elastic modulus of 180 x 10-³ N/mm², and thermal conductivity between 0.25 and 0.75 W/(m·K). They are resistant to radiation, organic solvents, acids (except hydrofluoric acid), and oils.
Quality and Design: Mica discs are available in various shapes and sizes, including elongated and angular ends. Custom designs are possible, and they can be up to 500 mm in length.
Additional Properties: The document includes a detailed table of properties such as crystallographic discoloration, air inclusion, mineral spots, and more, with symbols indicating whether these are permitted or prohibited.

Mica discs in longitudinal shape with square ends-1

Mica discs in longitudinal shape with square endsMica discs with angular ends made of muscovite natural mica USAGE Mica discs for borosilicate glass rods according to DIN 7081 as reliable heat protection and to ensure functionality Mica discs are an effective accessory for sight glass rods made of borosilicate glass according to DIN 7081. They serve as heat protection and as a protective layer between the process medium and the glass surface, especially in applications with aggressive media, superheated steam, or high temperatures. In conjunction with MAXOS® borosilicate glass rods according to DIN 7081, operating temperatures of up to 320 °C are possible. The mica discs significantly prolong 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 from thermal shocks. 1) Special dimensions possible Operating conditions: Through production and quality testing in the process flow, the property values of the mica discs and the narrow dimensional tolerances are guaranteed. With these excellent properties, mica discs can be used as additional safety designs, alongside sight glass plates, under extreme conditions. The mica discs provide a reliable protection function, especially under high thermal and chemical loads. They serve as a barrier against aggressive media, extend the service life of the underlying sight glass rods, and thus reduce maintenance costs and downtime of facilities. Moreover, precise processing ensures a uniform pressure distribution on the sight glass, which further increases mechanical stability. The flexible application possibilities of ACI mica discs make them an ideal addition 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!
