Abstract
A method for producing a mica based insulation is disclosed. The method comprises the steps of solubilizing a poly (carborane siloxane) containing carborane moieties linked by siloxy groups in a suitable solvent at a loading varying from 20 to 50% by weight of polymer on total weight of the solution, 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 by oxidative crosslinking of the polymer for a predetermined time interval and at a predetermined temperature above which oxidative crosslinking of the polymer becomes significant.
