Description

Rigid Mica Plate Mica Sheet 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 Mica Sheet 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 ℃ / 932 °F (In constant operation), 750 ℃ / 1382 °F (in intermit t ent operation) .

2: Phlogopite Rigid Mica Plate , Golden/Amber color, Heat resistance: 750 ℃ / 1382 °F (In constant operation), 1000 ℃ / 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 ℃ and 750 ℃ respectively, Peak work temperature are 750 ℃ and 1000 ℃ 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
