Mica Therm

Therm M&P (Thick Mica Plate) comes in the form of 2mm to 150mm thick rigid laminated plate after laminating, pressing and baking process, consists of quality muscovite or phlogopite mica paper impregnated with high temperature resistant organic silicon resin as binding agent.
Fire resistance classification UL94 (94 V-0); BS479 (class 1); NBN 21-203(A1), NFF16-101/2 (M0 u. F0)

Properties
Therm M&P is designed and developed for extreme requirements, requiring one or more of the following characteristics:
○ Extreme heat and flame resistance properties
○ Low thermal conductivity
○ Excellent electrical insulation properties
○ High mechanical strength, especially in compression, even at high temperature
○ Low sensitivity to chemical agents such as oil and greases
○ Asbestos free and non-toxic

Application
Therm M&P is widely applied as replacement of asbestos in industry as below:
○  Forging presses, hollow glassware industry
○  High voltage equipment
○ Construction of induction furnaces, arc furnaces and high frequency furnaces
○  Industrial sealing and gasket (e.g. oil & gas distribution)
○ Induction welding of saucepan bases in steel or metallurgy industry
