Abstract

See full text

Compositions comprising ferrosoferric oxide dispersed in a polymer matrix. Such compositions may exhibit properties suitable for achieving both resistive field grading effects and capacitive field grading effects e.g. in electrical stress control devices and surge arrestor devices. Such compositions may optionally include one or more capacitive field grading additives and/or conductive additives.
