Synthetic-plastic electrical insulation - 1942

During the year 1942 the plastics industry expanded still further. United States production in 1941, 438,000,000 lbs., was 58% over 1940 and it is estimated that 1942 surpassed 1941 by a very substantial percentage. In spite ,of this great increase, most plastics are in critical supply. The situation existent at the beginning of 1943 has been outlined by F. H. Carman, of W.P.B. (1). Vinyl chloride resins are almost completely allocated to war insulation in spite of very great expansion.
