📋 Mica Mineral Types
- • Muscovite Mica Sheet – potassium‑based, clear/white, excellent dielectric properties, up to 600°C.
- • Phlogopite Mica Sheet – magnesium‑based, amber/brown, superior heat resistance up to 900°C, good acid resistance.
- • Synthetic Mica (Fluorophlogopite) – lab‑grown, exceptional purity, up to 1100°C for aerospace and advanced electronics.
Our technical team can recommend the optimal type based on your operating temperature and electrical requirements.
🔧 Available Forms & Binders
- • Rigid Mica Plate – silicone bonded, up to 800°C, punchable for stamped parts.
- • Flexible Mica Sheet – shellac or acrylic bonded, up to 500°C, ideal for wrapping conductors.
- • Mica Paper/Composite – glass cloth reinforced, uniform thickness, cost‑effective for large panels.

Frequently Asked Questions
Q: What is the difference between Muscovite and Phlogopite mica sheets?
A: Muscovite (clear) is potassium‑based with excellent electrical properties up to 600°C; Phlogopite (amber) is magnesium‑based, handles up to 900°C and offers better acid resistance.
Q: Can you cut mica sheets to custom shapes?
A: Yes, we offer die‑cutting, stamping, drilling, and routing. Provide a drawing or template and we’ll produce accurate parts with tight tolerances.
Q: Are your mica sheets asbestos‑free?
A: Absolutely. All our mica sheets are 100% asbestos‑free, compliant with international safety standards (RoHS, REACH).
Q: What thicknesses are available?
A: Standard thicknesses range from 0.1mm to 5.0mm, with tolerances as tight as ±0.05mm. Custom thicknesses can be produced on request.
