Polymer-based synthetic materials are widely used in shipbuilding. Statistical data indicate an increase in accident-rate due to burns and inhalation of volatile toxic products of combustion. Toxicity data of some heat- and sound-proofing materials (ATM-1, FS-72, Vilares, Expanzit) studied at different temperatures are presented. Factors studied were loss of mass, products of combustion, CO2 release, and blood levels of carboxyhaemoglobin and LD sub 50 in white mice. Tabulated results show substantial differences in toxicity depending on the temperature, chemical structure, and rate of thermal oxidation. The least loss of mass occurred in ATM-1 (40% at 600 deg C and 30% at 800 deg C). This is a glass-based material with a low concentration of boron and phenolformaldehyde resin as binder. FS-7 sub 2 and Vilares showed high hydrocarbon concentration. FS-7 sub 2 had the greatest heat-resistance but maximum loss of mass occurred at 540 deg C. Vilares was decomposed at 280 deg C. Greatest loss of mass occurred in Expanzit at over 350 deg C. The separation of volatile compounds of combustion was governed by the temperature and the degree of gas liberation, and varied in all tested materials. The interrelationship between chemical structure, heat-resistance, thermal oxidation and liberation of volatile products has found to be of a sophisticated nature. Order from BSRA as No. 46,922.
