Mica Tapes

Our Mica Tapes marry the natural heat resistance of phlogopite or calcined mica paper with the mechanical support of fiberglass or polyester liners. Each tape is impregnated with a fully cured epoxy or silicone resin to create a seamless, crack-resistant wrap that withstands continuous operation in excess of 130 °C and short-term peaks above 800 °C. The supple construction allows tight, uniform winding around coils, cables, and bus bars, while the inorganic mica filler emits no harmful smoke or toxic gases under fire conditions. Designed for vacuum pressure impregnation (VPI) or dry-winding processes, these tapes retain at least 80% of their dielectric strength after prolonged immersion in transformer oil and resist degradation from chemical exposure, making them ideal for critical insulation layers in motors, generators, and specialty power cables.
