Fiber Glass Composites

General Details
Ruby Mica® Epoxy /Silicone Bonded Fiber Glass Composites are made by combining glass cloth with an epoxy/silicone resin as a binder, cured 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. Epoxy-based composites can withstand temperatures up to 250 – 300° C, whereas silicone-bonded composites can withstand temperatures up to 350 – 450° C.

APPLICATION

Highly temperature-resistant composite machined-parts for Ferro alloys submerged arc furnace and induction furnace insulation.

Slot packing insulation in HT motors, high-temperature washers in lifting magnets, etc.
