Product Description
Glass or Micanite or PET Film Tape
Ruby Mica* Glass I Micanite I 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-polejumpers, terminal bars, and various insulation purposes in turbo- generators.

FAQs of Glass Micanite PET Film Tape:
Q: How is Glass Micanite PET Film Tape used in electrical applications?
A: Glass Micanite PET Film Tape is applied to cover coils, wires, or parts of electrical insulation structures in equipment like motors and transformers. Its high dielectric strength and heat resistance make it ideal for preventing electrical leakage and protecting sensitive components.
Q: What benefits does this tape offer compared to standard insulating tapes?
A: This tape combines the strength of PET and mica to provide excellent thermal stability, superior oil resistance (only 0.5% absorption), and enhanced durability, making it more suited for high-temperature and industrial applications than ordinary insulating tapes.
Q: When should this tape be replaced or checked for effectiveness?
A: It is recommended to inspect the tape periodically, particularly after the 6-month shelf life. If signs of wear, reduced insulation, or physical degradation are observed, the tape should be replaced to maintain safety standards.
Q: Where is Glass Micanite PET Film Tape commonly used?
A: This tape is widely used in the electrical, electronics, and transformer manufacturing industries, as well as for maintenance and repair of electrical motors and high-voltage equipment.
Q: What is the process for applying this tape during insulation?
A: The tape is unwound from its roll and carefully wrapped or layered around the conductors or surfaces to be insulated, ensuring coverage is uniform and secure without overlaps or gaps. This ensures optimal insulation and performance.
Q: What makes the tape suitable for high-temperature environments?
A: Thanks to its high melting point range of 1250C to 1500C and low oil absorption, Glass Micanite PET Film Tape maintains its structural and insulating properties even under intense heat, making it reliable for harsh industrial settings.
