Abstract
Under the various conditions of pyrolysis, HCN, CO and other poisonous gases generated from polyurethane foam were examined. The results showed that, under the fuel rich air atmosphere, about 0.1 wt.% and about 4 wt.% of the initial polyurethane foam samples are converted into HCN and CO, respectively. This amount (wt.%) of HCN generated from polyurethane foam is only about 1/60 compared with that generated from polyacrylonitrile.
By the mass spectrometric analysis of the pyrolytic products from polyurethane foam, these products contained lower grade aliphatic hydrocarbons, alcohols, aromatic hydrocarbons and other various compounds and the complete analysis of all components was very difficult.
