Abstract:

Two components of plastic manufacture, n-butyl-phthalate and ethyl-methyl ketone, have been found in high concentrations contained in the low gaseous transfer coefficient polyethylene protective bag for the SPH-4 aviator helmet. These agents are the cause of the deterioration of the SPH-4 helmet polyether and polyurethane foam lining material. The use of mass spectrographic and gas chromatographic techniques provided the sampling of chemical compounds contained within the polyethylene bag. The solution to prevent foam liner deterioration is to remove the SPH-4 helmet from the protective bag. Author
