The insulating compound covered by this specification is intended primarily for use as a conductor insulation or as an insulating compound or belt for submarine communication and communication control cables and for shore and underground sections of cable connected thereto. It may also be used for other underground cables particularly in damp locations. The properties of the insulating compound are low dielectric constant and power factor, low water absorption properties, good physical and aging characteristics, stability of electrical characteristics after prolonged immersion, and long electrical life without physical deterioration during extended periods of storage.

The jacket compound covered by this specification is intended primarily for use as a protective jacket over the armor of submarine cables as protection against abrasion or the corrosive action of the bottom coils in which it is laid. It may be used for an outer jacket of non-armored submarine or underground cables. The properties of the protective jacket compound are good aging, stability of physical characteristics after prolonged immersion, and ability to protect the cable from abrasion or corrosive action.
