It is suitable for Class 220(R) electrical insulation systems. 3M Innovative Paper Technologies UL Recognized Insulation Systems may be found on UL’s Electrical Insulation Systems database at http.//database.ul.com/systems/. REACH Compliant and RoHS 2011/65/EU Compliant‎. 3M™ CeQUIN™ Inorganic Insulating Paper provides high thermal conductivity and long term dielectric strength. This paper is ideal for high performance electrical applications and provides low moisture absorption even under high humidity conditions. It is compatible with commonly used impregnating varnishes and resins, and partially discharges the effect of long term electrical stress based on its insulation qualities. This paper is ideal for dry type transformers, coils, reactors, traction motors, generators, battery separators, capacitor and electromagnet layer insulation.
