Thick Mica Plates
Insulac Mica Insulation Plate is manufacture using best quality Muscovite or Phlogophite Mica paper with Silicon resin binder under specific heat and pressure to produce Rigid and flat surface sheets.
Mica plates have very good electrical and mechanical properties. Fully resist against high heat with excellent electrical insulation. It is well suited for any machining into any shapes.It is widely used for Arc Chutes, Bus bar supports, Furnace Lining, Induction furnace, Resistor banks, Insulation of high heating area etc.
