R-5660-H series of Rigid Mica Plate
is mica laminates designed for providing outstanding electrical
insulation at high temperature, which consist of approximately 90 %
Muscovite (or Phlogopite) and 10% high temperature resistant silicone
resin. R-5660-H series has two species:
R-5660-H1: Muscovite Rigid Mica Plate, Silver color, Heat resistance:
500℃/932°F (In constant operation), 750℃/1382°F (in intermittent operation) .
R-5660-H3: Phlogopite Rigid Mica Plate, Golden/Amber color, Heat resistance:
750℃/1382°F (In constant operation), 1000℃/1832°F (in intermittent operation) .
According to different mica papers:
◆ R-5660-H1: Rigid mica plate
◆ R-5660-H3: Rigid mica plate
According to varying degrees of surface smoothness:
◆R-5660-G1:Muscovite smooth plate
◆R-5660-G3:Phlogopite smooth plate
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
◆ 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
◆ Excellent acid and alkali resistance, and oil resistance.
