Our products

Product category: Insulating, separating and special tapes

Polyimide Film 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.

PACKING
Tapes are packed in airtight mechanically strong boxes protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.

STORAGE
12 months at 20º C – Self – Adhesive Type
Unlimited at 25º C – Non – Adhesive Type

Glass/ Mica Resin-Rich Tape

Ruby Mica® Glass / MI. Resin-Rich Tape is a lamination of uncalcined muscovite mica paper with glass cloth. A thermo setting tri-functional epoxy novolac resin is used as a bonding agent making it a Class F insulation product. lhe tape is tack-free in cold conditions. An LDPE film interleaving Is used to prevent the tape interlayers from sticking to each other during ambient temperature fluctuations. 

Our resin-rich mica tapes make the coils electrically-stronger, and gives superior coil-heat dissipation capabilities. The homogeneous insulation produced after pressing and curing has a temperature-index of at least 155.

APPLICATION
Main slot wall insulation of bars / coils in HT motors and turbo-generators.. molded rigid larninate form can also be used to insulate commutators and form electro-thermal sleeve insulation for various applications.

AVAILABILITY
Tape roll / Folium /Wrapper:
Length : 25 – 500 m
Width : 20 – 1000 mm

PACKING
Tapes are packed in airtight robust boxes protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.

STORAGE
6 months at ≤ 20°C • 12 months at ≤ 5°C

Glass/ Micanite/ PET Film Tape

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. 

APPLICATION
Inter-turn and main insulation on end-windings of hydro-generators and motors with Class F insulation. Also used as a winding-component for bus bars, pole-to-pole jumpers, terminal bars, and various insulation purposes in turbo ­generators.

AVAILABILITY
Tape roll / Folium /Wrapper:
Length : 25 – 50 m
Width : 15 – 1000 mm

PACKING
Tapes are packed in airtight robust boxes protecting them from dirt, dust and moisture. The packaging also ensures safe transit and storage.

About us

Company details

Ruby Mica Co. Ltd. was established in 1968 for manufacturing the highest quality mica-based electro-thermal insulating materials catering to diverse industrial applications globally. Armed with over 45 years of experience, we have continuously evolved in accordance to the dynamic market needs for innovative insulation solutions for the electrical industry. Our state-of-the-art, fully-integrated manufacturing facility affords us complete control over the manufacturing process, right from product conceptualization phase to micro-product developmental stage, leading to ultimate customer satisfaction.

Dedicated to Innovation and Excellence

Capitalizing on the unique electrical and thermal characteristics of natural mica, Ruby Mica has developed a special insulation system catering to the high-voltage motor and generator industry. These high-performance materials have excellent workability with dielectric and thermal properties to match. Starting from the subtle techniques of mica-taping on conductor coils to the VPI process, our products are fine-tuned to perform to exacting parameters.

We strongly believe that good ingredients make a great end-product; hence we start by manufacturing the highest-grade of mica paper ourselves; picking recommended backing-materials and laminating them using world-renowned binding resins that keep product-aging in check besides granting them a longer shelf-life.

Over the years we have emerged as a one-stop shop for complete high-voltage rotating machine insulation systems. Our status as an approved vendor to large corporates like Indian Railways (Chittaranjan Locomotive Works, Diesel Modernization Works), Bharat Heavy Electricals Limited (Bhopal & Haridwar), and others, bears strong testimony of our capability, expertise and commitment to quality. A highly-reliable product and honest pricing-policy comes as standard when you deal with us.
