Abstract:

The insulation coatings from five commercial aircraft cables were pyrolysed in an inert atmosphere and most of the volatile degradation products identified by combined gas chromatography-mass spectrometry. The principal pyrolysis products of non-fluorine containing insulation systems were carbon monoxide, methane, carbon dioxide, ethylene, propylene and benzene. Insulations based on polytetrafluoroethylene PTEE and a copolymer of hexafluoropropylenetetrafluoroethylene FEP gave low molecular weight fluorine containing compounds as well as carbon monoxide and carbon dioxide. Pyrolysis of an insulation material based on silicone rubber produced appreciable amounts of silicon containing cyclic compounds. Author
