Glass PET Film Tape

Ruby Mica® Glass / Mica / PET Film Tape is a lamination of uncalcined muscovite mica paper with PET film one side and glass cloth on the other, making it a three layer high-performing mica tape. What makes this tape truly special is its unique blend of high tensile-strength imparted by glass cloth, strong electrical-resistance borrowed from the PET film, and superior thermal-endurance brought about by the use of best-quality mica there is. These tapes can withstand the rigorous overhang taping operation through sharp bends and curves without loosing their insulation value. They can be supplied in two different insulation classes. Class H insulation uses only the high thermal-grade silicone resin or modified polyester resin as a binder, whereas Class F insulation uses an epoxy resin as a binder.

Less space constraints give way to a thicker insulation for the coil overhangs. An additional fourth layer of PET film may also be laminated on the glass cloth side. This PGMP Tape has an increased dielectric value, better tensile-strength and provides a seamless mica tape-lapping on the coils.
