PET / Mica Tapeis a lamination of PET film and calcined muscovite mica paper.The self-adhesive version has excellent tackiness due to the presence of an uncured pressure sensitive resin on polyester film side. The LDPE film interleaving acts as a separator preventing the tape interlayers from sticking to each other. Non-adhesive version is tack-free and cornes without LDPE interleaving. PM tape is available for both Class F & Class H applications.
An additional layer of PET film may also be laminated on top of mi. paper.ThisPMP Tapehas an increased dielectric value, better tensile strength, and easier workability.
APPLICATIONConductor coil inter-turn insulation, and as a wrapper in main coil insulation of an induction furnace.

Glass / Mica / PET Film Tapeis 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. ThisPGMP Tapehas an increased dielectric value, better tensile-strength and provides a seamless mica tape-lapping on the coils.
APPLICATIONOverhang Insulation of the coils / bars in HT motors and generators due to its high thermal, dielectric and mechanical values.
PGMP wrappers are used for ground-insulation in HT motors and generators as well.
Superior flexibility and high mechanical-strength, renders our GMP / PGMP tapes hand as well as machine-taping compatible.

Ruby Mica Glass / Micanite / PET Film Tape is a lamination of single-layer high-quality muscovite natural mica splitting with PET film on one side and glass cloth on the other, bonded together using an isophthalate alkyd varnish. Due to the presence of mica in its natural form, this tape has high resilience, flexibility and impact-resistant properties.

Ruby Mica Uniform Kapton / Mica Tape is a lamination of calcined muscovite mica paper with a Kapton Polyimide Film. Mica paper is further reinforced with Aramid Fibroids, to aid an evenly spread, high thermal-grade silicone resin impregnation.
This mica tape being drastically thin spares more room for the conductor, thus helping in size-reduction of the HT motor. It almost sketches the perfect coil-insulation; surpassing the best of all insulation attributes.They have a very high partial-discharge resistance along with increased thermal-conductivity, enabling the HT motor to run cooler for longer.
Ruby Mica GMPCAB Tape is a lamination of uncalcined phlogopite/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-sustenance brought about by the use of the best quality mica there is. A high thermal-grade silicone resin is used as a binder, making it a class H insulation product.
An additional layer of PET film secures the mica paper in its position at all times, while providing a seamless mica tape lapping on the wires. The addition of PET film to the glass mica tape reduces the hassle and one time-consuming activity for the cable companies who wrap a single layer of PET film on their cables after wrapping the glass mica tape as well.PET film adds on 3.5kV of break down voltage protection to electric cables operating below 120C. We ran a lot of suitability tests in our labs in order to study the behavior of PET film at different temperature increments and found out that it simply vanishes without a single trace at 600C. Thus you can rest assured that the PET film enhances the mica tapes workability multi-fold without altering its fire-fighting properties in any way.
