ABSTRACT:
New high voltage insulating compositions are disclosed. The compositions comprise a polymer (e.g. a polysiloxane, epoxide resin or a polymer of one or more olefins or substituted olefins), an antitracking additive (e.g. an alumina hydrate), and certain phosphorus-containing compounds which have been found to provide the compositions with greatly improved resistance to erosion by high voltage stress. The phosphorus-containing compounds include phosphonates, phosphates, phosphites, phosphinates, phosphonites, phosphinites, phosphine oxides and sulfides, and phosphines, and salts and complexes thereof. The phosphorus-containing compound can react in situ with the polymer or other ingredients of the composition.
