ABSTRACT:
A mica based electrical insulation for high temperature applications comprising reconstituted micaceous sheets impregnated with an impregnant of the family of poly (carborane siloxane) containing carborane moieties linked by siloxy groups at approximately 2-25% by weight of impregnant based on total weight of impregnated mica. The method for producing the mica based electrical insulation comprises the steps of solubilizing a poly (carborane siloxane) in a suitable solvent at a loading such as to produce a final insulation composite containing the desired weight of impregnant, placing a mica sheet of desired thickness on a suitable support, impregnating the supported mica sheet with the solution so as to achieve complete wetting, and curing the impregnated mica sheet for a time interval and at a temperature sufficient to effect cross-linking of the polymer.
