Thick Mica Plate

product No:R-5660-T
Unit:KG

Introduction
R-5660-T series of Thick Mica Plate is Rigid Mica Plate with thickness over 5mm, it is mica laminates designed for providing outstanding resistant to high voltage and to high temperature. R-5660-T series has two species:
R-5660-T1:  Muscovite Thick Mica Plate, Silver color, Heat resistance: 500℃/932°F (In constant operation),  750℃/1382°F  (in intermittent operation)  .
R-5660-T3:  Phlogopite Thick Mica Plate, Golden/Amber color, Heat resistance: 750℃/1382°F (In constant operation),  1000℃  /1832°F (in intermittent operation)  .


Types
According to different mica paper:
◆ R-5660-T1: Extra-thick muscovite plate
◆ R-5660-T3: Extra-thick phlogopite plate


Properties
Relative to general insulation material, the prominent advantages of the extra-thick mica plate are:
◆ Superior heat insulation performance, fire-resistance up to temperature of 500℃-750℃, low thermal conductivity;
◆ Oil and corrosion-proof, environmental protection and non-toxic, as the alternatives of asbestos;
◆ High bending strength . It can be processed by lathe, milling machine, drilling machine into various shaped piece
without layer separating.
