insulation phlogopite mica roll

Phologpite mica roll is a result of specially pressed mica product which is made of phologpite mica paper and silicon resin. The thickness ranges from 0.2mm to 0.8mm, breakdown voltage is above 15KV, tensile strength is above N/15mm and temperature resistance is above 800°C.      This is a flexible material made from silicone bonded phlogopite mica paper laminated on one side with closely woven glass fabric. This is an economic grade of induction furnace slip-plane material. The mica provides the smooth slip plane and consequently is usually positioned facing the main refractory lining.The woven glass cloth provides the material with additional mechanical strength and is usually placed against the induction coil.   Type   ST-RMGM: phlogopite mica paper with glass fiber cloth inside. ST-RGMG: phlogopite mica paper with glass fiber cloth on double sides.
ST-RMG: phlogopite mica paper with glass fiber cloth on one side.
ST-RCMG: phlogopite mica paper with glass fiber cloth and ceramic fiber paper on each side.   AVAILABILITY
