Mica Plate

Specifications

1.Excellent resistance to heat up to 1000 degrees
2.Excellent electrical insulation
3.Environmentally safe

Description

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.Rigid Mica Plate has acquired UL94V-0 approval

with the file No.E231452, TUV approval on environmental safe(the file No. Z05811263 ),

SGS-RoHS approval with the file No. SH6148278/CHEM, and has been authorized for

use in contact with food products (certificate from the FDA with the file No. RJSSZ060586FDA).

 

Rigid Mica Plate has two species:

1: Muscovite Rigid Mica Plate , Silver color, Heat resistance: 500 °C / 932 °F

(In constant operation), 750 °C / 1382 °F (in intermit t ent operation) .

2: Phlogopite Rigid Mica Plate , Golden/Amber color, Heat resistance: 750°C / 1382 °F

(In constant operation), 1000 °C / 1832°F (in intermittent operation) .

 

Features

•Excellent resistance to heat up to 1000°C. It has unique temperature resistance,

the maximum working temperature for the Muscovite Mica Plate and Phlogopite Mica

Plate are approximately 500 °C and 750°C respectively,Peak work temperature are

750 °C and 1000 °C respectively.

•Excellent electrical insulation. It has excellent dielectric properties, the maximum

dielectric is more than 20KV/mm.

•Excellent punchability. It has good flexural strength and can be cut very precisely

using die-stamping.

•Environmentally safe. It generates very little smoke even at excessive temperatures
