General Details
Ruby Mica® Flexible Mica Sheet is made by combining muscovite or phlogopite mica paper with an inorganic silicone-resin binder under specific heat and pressure. It has excellent flexibility, heat-resistance, moisture-resistance and di-electric properties. It does not emit smoke or odor upon heating up.

Muscovite mica paper-based material can withstand temperatures up to 600° C whereas phlogopite mica paper-based material can withstand temperatures up to 800° C. The product is IEC 60371-3-3 compliant. Flexible mica sheets can also be made using a B-Stage epoxy resin as a binder. These sheets have excellent adherence to metal surfaces.
