  • Process for producing composite insulating material
    Patent number: 4332836
    Abstract: A process for the production of a composite insulating material is described. A mica paper is coated with a curable admixture of resin material and crosslinking agent. The coated tape is then passed through a zone of radiant energy to effect at least partial cure of the resin. Reinforcing sheet(s) may also be laminated to the paper through the resin to produce multilayer materials.
    Type: Grant

  • Dielectric films with increased voltage endurance
    Patent number: 4308312
    Abstract: A dielectric film with improved voltage endurance is disclosed. The dielectric film is provided with an aluminum oxide powder dust coating which increases the life of the film by improving the voltage endurance. A film comprising mica reinforced with polyester and/or glass is especially useful in the manufacture of insulating tapes and cloths found in electrical devices. Best voltage endurance is provided by fumed aluminum oxide particles which are in the colloidal size range and which are more than 99.5% pure.
