Product Overview
Our High-Temperature Mica Sheets are engineered for extreme thermal insulation and electrical resistance. Manufactured using high-quality Phlogopite (or Muscovite) mineral paper impregnated with heat-resistant silicone resin, these sheets provide excellent stability at temperatures up to 1000°C.
Available in both Rigid (for structural support) and Flexible (for wrapping) forms, they are the ideal solution for induction furnaces, microwave ovens, and aerospace insulation applications where safety and durability are non-negotiable.
🔥 Extreme Heat Resistance
Withstands continuous operating temperatures of 500°C (Muscovite) to 1000°C (Phlogopite) without deformation.
⚡ Superior Insulation
Dielectric strength greater than 20kV/mm effectively prevents electrical arcing in high-voltage equipment.
🛡️ Eco-Friendly & Safe
UL 94 V-0 flame retardant certified. Low smoke emission and asbestos-free composition.

What is a mica sheet used for? +
Mica sheets are primarily used for electrical and thermal insulation. Common applications include slip-planes in induction furnaces, waveguide covers in microwave ovens, and thermal barriers in automotive battery packs.Is mica sheet electrically conductive? +
No, mica is an excellent electrical insulator (dielectric). It blocks the flow of electricity while allowing heat to pass through (thermal conduction) or resisting heat transfer, depending on the orientation.Can I use my microwave without the mica sheet? +
No, it is risky. The mica sheet protects the magnetron (the component that generates microwaves) from food splatters. Using it without the sheet can cause arcing and permanent damage to the magnetron.What is the difference between Muscovite and Phlogopite? +
Muscovite (White Mica) has better electrical properties and withstands up to 500°C. Phlogopite (Gold/Green Mica) is softer but has superior heat resistance, withstanding continuous temperatures up to 1000°C.What temperature can mica sheet withstand? +
It depends on the mineral type. Muscovite mica withstands up to 500°C (932°F), while Phlogopite mica withstands up to 1000°C (1832°F).Is mica sheet hazardous to health? +
Finished mica sheets are generally non-hazardous. However, mica dust generated during cutting can be harmful if inhaled. Always wear a dust mask when machining mica products.Is mica sheet waterproof? +
Mica itself has very low water absorption (<1%). However, as the sheets are bonded with resin, they are moisture-resistant but not typically designed for long-term submersion in water.
