Flexible mica plate

product No:R-5660-S
Unit:KG

Introduction
R-5660-S series of Flexible Mica Plate is a good heat resistant insulating material, which retains its permanent flexibility at room temperature. R-5660-S series has two species:
R-5660-S1:  Muscovite Flexible Mica Plate, Silver color, Heat resistance: 500℃/932°F (In constant operation),  750℃/1382°F  (in intermittent operation)  .
R-5660-S3:  Phlogopite Flexible Mica Plate, Golden/Amber color, Heat resistance: 750℃/1382°F (In constant operation),  1000℃  /1832°F (in intermittent operation).


Types
According to different mica papers:
◆ R-5660-S1: Muscovite flexible plate
◆ R-5660-S3: Phlogopite flexible plate


Properties
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.
