Ruby Mica Co. Ltd


Rigid Mica Sheets




We have carved a niche in offering supreme quality Rigid Mica Sheets. Known for their excellent rigidity, heat resistance, moister resistance and di-electric properties, our Rigid Mica Sheets have become the preferred choice for domestic appliances and industrial heating elements. Working temperature is limited from 250 to 300 degree Celsius. Further, Rigid Mica Sheets are available in a wide range of different dimensions to suit all the requirements of our valuable customers.

 

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, 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 600 oC whereas, phlogopite mica paper-based material can withstand high temperature up to 800 oC. 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 temperatures is limited to 250 oC – 300 oC. They are mainly used for commutator-segment insulation.

Application : Heating-elements 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.
