Catalyzed mica tapes for electrical insulation

摘要

A catalyzed mica tape used in insulating electrical conducting devices is made from a mica paper bonded to a backing with a bonding resin. The bonding resin is cross-linkable by an addition reaction. The catalyzed mica tape has distributed therein at least a catalyst at a concentration of greater than 0.01 g/m2 for every 100 g/m2 of the bonding resin. The catalyst is an organo-transition metal compound, organo-tin compound, or a combination thereof.
