Rigid Mica Sheet

Product Description

Silicone Bonded Flexible Mica Sheet

Ruby Mica Rigid 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 rigidity, 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. Since the binder plays a critical role in the overall product performance, the best commercially-available resin,with as much as 82% solid silicone content,is imported from Germany for excellent results.

Muscovite mica paper-based material can withstand temperatures up to 600C whereas, phlogopite mica paper- based material can withstand high temperatures up to 800C. The product is IEC 60371 -3-3 compliant.

A choice of epoxy resin is also available as a binder. Ruby Mica Epoxy Rigid Mica Laminates have higher rigidity, highly-uniform surface profile and weatherproof properties when fully cured. However, the working temperature is limited to 250oC - 300C. They are mainly used for commutator-segment insulation.

Application

Heating-element supports, winding-cards and cover-plate insulation in domestic appliances and industrial-heating elements. Its superior chemical-resistance makes it an ideal battery-cell separator. Highly temperature-resistant mica machined parts for complete Ferro alloys submerged arc furnace and induction furnace insulation. Dynamic breaking resistors in railways and plate-insulation in heated presses.

Thermocouples and conductor insulation.
