Flexible Mica Laminate

General Details
Ruby Mica® Flexible Mica Laminate is made by combining uncalcined 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 is a completely asbestos-free and highly chemical-resistant insulation having low thermal-conductivity. 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 high temperatures up to 800° C. The product is IEC 60371-3-3 compliant. Flexible mica laminates can also be made using a B-Stage Epoxy resin as a binder. These sheets have excellent adherence to metal surfaces.
