Yunshui® Muscovite paper maintains the excellent electrical and high-temperature properties of natural white muscovite flakes. It 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. To form roll or strip heat-resistant insulation materials by impregnation and lamination with epoxy or organic silicone resin.


Properties:
  • Good corona resistance and cutting resistance.
  • Good permeability and breathability.
