ABSTRACT:
Improved synthetic resin insulators having enhanced arc track resistance and reduced UV light degradation characteristics are provided which include a continuous resin phase and a discrete, discontinuous hydrophobic phase in the form of discrete, suspended droplets within the resin. The preferred insulators are formed of a continuous epoxy matrix having suspended droplets of petrolatum dispersed therein. The resin phase comprises from about 15 to 50% by weight of the composition, whereas the hydrophobe is present at a level from about 2 to 10% by weight. UV light resistance is improved by predissolving or predispersing a quantity of UV light absorber in the hydrophobe before the latter is mixed with the resin phase. Use of a hydrophobe which is solid at normal temperatures but which melts above about 80.degree. F. (such as petrolatum) results in lower dust attraction during ordinary conditions and the ability to melt and effectively encapsulate surface dust during periods of increased arcing activity.
