Heat resistant mica sheet
Types of Mica sheet
According to different mica plate:
* H1: Hard mica plate
*H2: Hard mica plate
According to varying degrees of surface smoothness:
*H1:Muscovite smooth plate
*H2 :Phlogopite smooth plate
Feature for mica sheet:
Relative to general insulation material, the prominent advantages of the flexible mica plate are:
*Excellent insulating properties at high temperature: At 500-1000℃ operating ambient temperature, the voltage breakdown resistance is 15KV/mm;
*Good tensile property: It can be processed into a variety of shapes without layer separation;
*Excellent environmental protection performance: The product contains no asbestos, and has less smoke and odors, even smokeless and odorless when heating;
*Excellent acid and alkali resistance, and oil resistance.
