Smooth muscovite mica sheets


 



Product certification:




Types:

By mica paper, resin and properties, mica plates have following types:

Classification	Tpye	R-Properties
Mica Plate	Muscovite Plate  Phlogopite Plate	Heat Resistant 500 °c  Heat Resistant 800 °c
Hardness grade	Rigid Plate  Flexible Plate	Hard  Soft
Surface	Matt Plate   Glossy Plate	Surface Rough  Surface Glossy

 
Rigid Mica Plate:

1. Rigid laminated material are known by its excellent thermal resistance, good flame resistance, high dielectric strength, excellent physical strength, and little smoke by heating.
2. The products have been widely used in the industries of household electric appliances (clothes irons, hair dryers, toasters, kettles, cooking appliances, microwave ovens, air heaters), metallurgy (frequency furnace, intermediate frequency furnace, arc furnace), medical appliances, etc.

Flexible Mica Plate:

Flexible Mica Plate is a kind of flexible laminated material, it has excellent dielectric properties , excellent tensile strength and easy to form at room temperature. They aways used in hair dryers, curlers, electrical irons, motors and so on.
 
Glossy Mica Plate:

Glossy Mica Plate are made from muscovite (or phlogopite) mica paper and high temperature resistant silicon resin,  it is compared with rigid mica plate, its surface are very smooth, but properties have no different. Glossy Mica Plate  has two species: Glossy muscovite mica plate and Glossy Phlogopite mica plate.
