R-5660-S series of Flexible Mica Plate is a good heat resistant insulating material, which retains its permanent flexibility at room temperature. The product consists of approximately 90 % Muscovite (or Phlogopite) and 10% high temperature resistant silicone resin.

R-5660-S series 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).

R-5660- S series has two species:
    > R-5660- S 1: Muscovite Flexible Mica Plate , Silver color, Heat resistance: 500 ℃ / 932 °F (In constant operation), 750 ℃ / 1382 °F (in intermittent operation) .
    > R-5660- S 3: Phlogopite Flexible Mica Plate , Golden/Amber color, Heat resistance: 750 ℃ / 1382 °F (In constant operation), 1000 ℃ / 1832°F (in intermittent operation) .

R-5660- S series are flexible and can be permitted winding or wrapping into place without heating. They are used as linings, covers or backings, as a separating sheet or insulating sheet, the application is: Heat gun, Hair dryers, Fan heaters, Circuit breakers, Transformers, Electric furnaces, Generator, Magnetic Coil, and Coil Insulation etc.
