Yunshui® Phlogopite mica paper is made from high-quality phlogopite mica as raw material, which is processed through processes such as hydraulic pulping, dehydration concentration, scale ratio, and forming. It has excellent high-temperature resistance and can be impregnated and pressed with epoxy resin, organic silicone resin, etc. To form high-quality plate-like heat-resistant insulation materials. It can also be combined with fiberglass cloth, thin film, ceramic fibers, etc. Through epoxy or organic silicone resin impregnation to form rolls or strips of high-resistant insulation materials.


Properties:
  • Good voltage resistance performance.
  • Temperature resistance above 750℃.
