Yunshui® Mica paper has excellent electrical and thermal resistant properties, good electric arc and corona resistance, suitable penetration and high air porosity which acted a positive effect on final mica products such as high-quality plate-shaped, roll or ribbon-shaped insulating materials impregnated with epoxy resin, silicone resin and reinforced with fiber glass,film or ceramic etc.


Properties:
  • Excellent voltage resistance, Temperature resistance above 750℃;
  • Used for fire-resistant wire&cable after being made into mica tape.
