Buy low price high quality Muscovite Mica Tape for Insulation. Muscovite Mica Tape is a high-temperature insulating material made from muscovite mica paper bonded with a silicone resin or other heat-resistant binder and often reinforced with glass fiber or polyester film. It’s widely used for electrical insulation, especially in fire-resistant cables.
Key Features of Muscovite Mica Tape:
Base Material: Muscovite Mica (KAl₂(AlSi₃O₁₀)(OH)₂)
Temperature Resistance: Up to 950°C – 1000°C
Fire Resistance: Maintains insulation under flame for over 3 hours
Dielectric Strength: High (usually > 20 kV/mm)
Flexibility: Can be wrapped around conductors
Low Smoke & Toxicity: When used in fire scenarios
