Compositions suitable as electrical insulation comprised of synthetic dielectric polymer, mica flakes having specific surface area of about 7 square meters per gram or greater and a minor amount of a silicone resin that is substantially compatible but not reactive with the polymer. The compositions can withstand high electrical voltages over extended periods of time (being extremely resistant to corona breakdown) and also have good mechanical properties (e.g., toughness, strength and flexibility). |
