The Electrical, Mechanical and Thermal Properties of Mica make it the best insulation
material in the earth. The Mica Scrap and waste is used to make reconstituted Mica paper,
which is used to make different kinds of electrical and thermal insulation material.
The properties of mica mineral are retained by using Mica paper
with different bonding agents like, Epoxy and Silicon. The bonding agent are used as per
requirement of application
SmithLamina Heater Mica Plate is manufacture using best quality Muscovite or
Phlogophite Mica paper with Silicon resins binder under specific heat and pressure

SmithLamina epoxy mica sheet for commutator consist of Muscovite or phlogopite mica
paper, impregnated with a specially selected epoxy resin. It performs good
electrical properties, mechanical strength, and excellent moisture resistance.
Application :-
This product is a hard, dense mica sheet for use in segments, separators and
spacers. It can be sawed, sheared
and punched into intricate shapes using good commercial practice. Because of its
superior uniformity, automatic feeding and stacking are possible for cost savings in
high speed assembly operations.
