Insulating Tape

Paper Mica tape is processed by stacking mica paper to desired thickness and bonded to each other with a high temperature resisting resins on glass cloth reinforcement backing material. It is then set to sheet form by applying hot press being passed through heated rollers. They are produced in rolls and slitted to required width.

When the applied layers of Mica Paper Tape are subjected to heat and pressure, the resin flows before gelling and then curing to give a sealed flexible structure of high dielectric and mechanical strength. Major applications of the material are cable, motor, and transformer layer insulation.
