R-5461 Mica Roll consists of phlogopite mica paper (or synthetic mica paper / calcined mica paper) impregnated with a special silicone resin on glass cloth (or biologic / harmless ceramic ) depending on application. The product has great flexibility and high tensile strength and can be used to create inorganic, fire-resistant insulation for fire resistant cables.
