Abstract
A corrugated, highly flexible mica insulating structure is disclosed which comprises one or more layers of mica paper impregnated with about 5 percent to about 25 percent by weight of a flexible polysiloxane resin having about 1 percent to about 4 percent by weight of an organic titanate and about 0.5 percent to about 2 percent by weight of a naphthenate based on polymer solids, said resin binder being partially cured or B-staged wherein the resulting papers are then corrugated to impart greater flexibility without a substantial loss of its dielectric properties.
