Fiber Glass Composites
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.
