Phlogopite Natural Mica 

When applications call for very high temperature resistance, Phlogopite natural mica, commonly referred to as “Amber”, is an excellent choice. Able to withstand temperatures up to and beyond 1200°F.  Can be sold in its raw or 'block' form and we can also offer fabrication to customers print or drawings. 

Please contact our sales team to discuss your technical needs, pricing and any questions you might have. 

Block and sheet mica are often used in electronics and electrical systems. They are used as insulators in electronic and thermal equipment, dielectrics in capacitors, decorative panels in lamps and windows, insulation in electric motors and generator armatures, field coil insulation, and magnet and commutator core insulation.
