Abstract

Phenol-formaldehyde foam was decomposed by non-flaming combustion under temperature and atmosphere conditions simulating the main stages of a fire development and the decomposition products were studied. The type and amounts of the products were affected by the decomposition conditions. The residue yield, which was large, decreased with increase in temperature and atmospheric oxygen. Volatile products consisted mostly of light gases with some volatile-condensable products. The volatile products included light hydrocarbons, formaldehyde, phenols, aldehydes, ketones, ethers, oxygen-containing heterocycles, fused ring compounds and benzene and its homologues. The concentration dependence on combustion conditions was studied.
