Mica Sheet Properties & Specifications

Mica has estimable electrical, physical, mechanical and thermal pertinacity properties. It has high transparency, optical clarity, flatness, non‑breakability and heat resistancy. As such, it is suitably used as windows in kerosene stoves, wood stoves, furnace peep‑holes and microwave ovens.

Mica eliminates risk of cracks, breakage, jerks and can easily withstand shocks, strains and vibration during operations at higher temperatures and prevent grassing. Mica also provides complete safety, versatility, durability and reliability and retains its basic strength.

Mica Sheets are available in any desired size and shape, such as RECTANGULAR, OVAL, CIRCULAR (ROUND) and can be supplied in any specified thickness. They are normally produced in standard thickness of .003" – .006" (0.075 – 0.15mm approx).
