Industrial Electrical Engg Company

Established since 1921

Rigid Mica Sheet (Silver Mica)

Usage temperature up to 600° C. to 800° C.

MUSCOVITE MICA & PHLOGOPITE MICA:

This is a strong rigid sheet material made by combining Muscovite Mica paper or Phlogopite Mica paper with a Silicon resin binder (Inorganic) under specific heat and pressure. It has excellent physical strength, heat resistance and electrical properties.
It does not emit smoke and odor.
Depending on the application. Muscovite mica or phlogopite mica paper based material is used.
