Lot of 100 pcs Transparent Insulating Mica Sheets 60mm x 50mm x 0.3mm

Length 60 mm, Width 50 mm, Thickness 0.3 mm.
Natural mineral stone mica from Siberia.
Produced at 1991 in Irkutsk Mica Factory, USSR.

Natural mica sheets are raw, mineral-based laminates peeled directly from mined mica blocks. Known for their perfect cleavage, they can be manually split into incredibly thin, uniform, and optically flat layers. They are highly prized across industries because they remain structurally stable at temperatures exceeding 600°C to 1000°C and serve as excellent electrical insulators.

Key Technical Properties

• Thermal Endurance: Naturally flame-retardant, handling sustained extreme heat environments without warping or breaking down.
• Dielectric Strength: Offers exceptional resistance to high voltage and electrical breakdown, making them perfect for sensitive circuitry.
• Chemical Inertness: Impervious to most acids, water, solvents, and chemical vapors.
• Optical Transparency: High-quality muscovite mica splits into virtually clear sheets that permit clean light transmission.

Common Applications

• Laboratory Substrates: Used as ultra-clean, atomically flat base plates for Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM).
• Electrical & Electronics: Found in high-frequency capacitors, heating element cores, radio-frequency components, and power transistors.
