Glass Mica Tape, For High Temperature

Ruby Mica® Glass Mica Tape is a lamination of uncalcined muscovite / phlogopite mica paper with glass cloth. High thermal-grade silicone resin is used as a bonding agent making it a Class H insulation product.

Highly-porous mica paper is selected which has excellent resin absorbing properties. The GM Tape’s good flexibility with minimal thickness contributes to the ease in conductor taping.

An additional layer of glass cloth may also be laminated on top of mica paper. This GMG Tape has an increased thermal conductivity for better coil-heat dissipation and nearly doubles the tensile-strength of GM tape.
