Review of synthetic plastic electrical insulation

The 1939 literature on plastics has kept pace with their rapidly expanding commercial development. Among the many general reviews, only a few can be briefly mentioned. “Modern Plastics” (148,149) rather completely describes developments during 1939. W. A. Hamor (150) discusses many of the newer resins, both in America and Europe. “Electrical Manufacturing” (151) compares the properties of plastic and ceramic insulators, and includes a list of companles making such materials. Kausch (153) in his handbook (second edition) thoroughly covers all commercial resins. The fields of insulation finishes, sheet and rod materials, and continuous wire insulation are summarized by Halls (153,154) and Stillwagon (155). Other reviews are included in the bibliography (156–179).
