Mica paper
JR series mica paper is a continuous web paper produced by hydraulic stripping or chemical pulping with high-quality muscovite, phlogopite or synthetic mica as raw materials. Mica paper has excellent electrical performance, high temperature resistance, and good permeability. It can be impregnated and pressed into high-quality plate-type heat resistant insulating materials with epoxy resin, silicone resin, etc., and can also be impregnated and compounded with glass fiber cloth, film, ceramic fiber, etc. into high-quality ribbon heat resistant insulating materials with epoxy or silicone resin.
