Stressed, clean beryllium copper wires were subjected to fumes of selected plastics and fluxes under both humid and dry environments. Macro-visual and microscopic examinations, as well as resistance value changes, were noted. PVC, and one-component RTV silicone rubber, were found to be extremely corrosive. Acetal, nylon, polyurethane foam, and teflon were found to be non-corrosive. A series of one-component RTV silivones were evaluated to determine their true curing time by measuring the complete cessation of gaseous evolution under normal laboratory conditions. Teflon emitted volatile material during exposure to high humidity at 70 C. The vapors were deposited on various surfaces where they polymerized into visible white plastic films of fluorocarbon polymer. Author, modified-PL
