Product Description
Resin Rich Glass Mica Tape
Ruby Mica Glass / Mica 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. The 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. Its molded rigid laminate form can also be used to insulate commutators and form electro-thermal sleeve insulation for various applications.

FAQs of Resin Rich Glass Mica Tape:
Q: How is Resin Rich Glass Mica Tape applied in electrical insulation systems?
A: Resin Rich Glass Mica Tape is typically wrapped or layered onto motor coils and turbo generator windings to provide robust electrical insulation, protecting against heat, moisture, and electrical discharge.
Q: What benefits does a high CaO content (minimum 90%) offer for mica tapes?
A: The elevated CaO content enhances thermal stability and insulation properties, enabling the tape to withstand high operating temperatures and maintain performance under rigorous conditions.
Q: When should Resin Rich Glass Mica Tape be replaced or checked for integrity?
A: It is advisable to inspect and potentially replace the tape during routine maintenance or if signs of wear, degradation, or reduced insulation performance are detected, especially within its 6 to 12 month shelf life.
Q: Where is Resin Rich Glass Mica Tape most commonly used?
A: This tape is widely used in electrical manufacturing and repair facilities, primarily for insulating motors and turbo generators in industrial settings throughout India and for export markets.
Q: What is the process for manufacturing Resin Rich Glass Mica Tape?
A: The tape is produced by impregnating fine mica powder with resin, layering it with glass for structural support, and then cutting or winding into precise lengths for easy application.
Q: How does the low oil absorption benefit the longevity of the tape?
A: Low oil absorption (0.5%) minimizes the risk of contaminant ingress, preserving the insulations integrity and extending the operational life of equipment.
