Ruby Mica Company Limited Giridih, Jharkhand

Ruby Mica® V-Rings are made using alkyd vinyl bonded mica splitting-based sheets. The flexible-sheet cut-pieces are molded and form. to a V-Ring shape using heavy cast-iron molds. These molds are subjected to high heat and pressure for a final curing-cycle, yielding a rigid V-Ring.They are ground to a final finish with precise thickness and surface-finish. These V-Rings are highly-customizable and therefore can be molded to desired shapes and sizes.

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® Uniform Glass / Mica Tape Is a lamination of high thermal-grade phlogopite mica paper with glass cloth. Mica paper is further reinforced with Aramid® Fibroids, to aid an evenly spread, high thermal-grade silicone resin impregnation.

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.

Application : Fire Protection

Brand Name : Ruby Mica Uncalcined Mica Paper

Type : Muscovite

Material : Mica

Application : High Temperature

Type : Insulation Sheet

ruby mica® rigid mica laminate is made by combining uncalcined muscovite or phlogopite mica-paper with an inorganic silicone-resin binder under specific heat and pressure. it has excellent rigidity, heat-resistance, moisture-resistance and di-electric properties. It is a completely asbestos-free and highly chemical-resistant insulation having low thermal-conductivity. It does not emit smoke or odor upon heating up. Since the binder plays a critical role in the overall product performance, the best commercially-available resin, with as much as 82% solid silicone content, is imported from germany for excellent results. muscovite mica paper-based material can withstand temperatures up to 600°c whereas, phlogopite mica paper- based material can withstand high temperatures up to 800°c. The product is iec 60371-3-3 compliant. a choice of epoxy resin is also available as a binder. ruby mica® epoxy rigid mica laminates have higher rigidity, highly-uniform surface profile and weatherproof properties when fully cured. However, the working temperature is limited to 250°c – 300°c. They are mainly used for commutator-segment insulation.

Thickness : 0.1 to 75 mm

Ruby Mica® Rigid Glass Mat consists of highly heat-resistant chopped-glass strands composed into a uniform mat by impregnating it with a special varnish.

Brand Name : Ruby Mica Tape

ruby mica® polyimide film tape is a dupont® kapton® film based tape. Dupont® is one of the earliest innovators of polyimide film. Its kapton® film imparts excellent di-electric and thermal stability to the conductor strands for their long and efficient service life.   application bare copper conductor strand insulation of coils in ht motors & generators. availability these kapton® film tapes are slit to desired widths and lengths. A choice of self-adhesive or non-adhesive version of the product is also available. storage 12 months at 20º c – self – adhesive typeunlimited at 25º c – non – adhesive type data is based on tests performed by ruby mica. Users are advised to verify and ensure suitability for intended applications. The above product can be tailored according to your desired specifications.
