Chapter VII rubber insulation

The most interesting developments during 1953 have been the improvement in properties of silicone rubber and their more widespread use for electrical insulation. Silicone and other synthetic rubbers are becoming important in the field of dielectrics. Aging, oxidation, and cracking are the major problems with rubber insulation which were studied in 1953. Fundamental and practical solutions to many phases of these problems may be forthcoming which will bring about in the future rubber insulation of high quality, good aging characteristics, which is adaptable for use at 300°F or higher.
