Yunshui® Calcined muscovite paper maintains the excellent electrical and high-temperature properties of natural mica, and can be impregnated and composite with fiberglass cloth, thin films, etc. Through epoxy or organic silicon resin to form high-quality rolls or strips of high-temperature resistant insulation materials.


Properties:
  • Good dielectric performance with low dielectric loss.
  • Excellent temperature resistance performance.
  • Higher mechanical strength.
  • Can replace chemical pulp cooked paper.
