Abstract
Pyrolysis gas chromatography/mass spectrometry (GC/MS), thermogravimetric analysis (TGA), NBS Smoke Chamber tests, oxygen index tests, flame spread tests, and toxic gas production tests have been used to study the fire and flammability characteristics of two styrene cross-linked polyester resins, Vibrin F1029 and Hetron 692TP, and three resol phenolic resins, J2018L, OCFHJ1 and Plenco 11956. The results indicate that the phenolic resins are superior to the polyester resins from a 'fire and flammability' point of view. That is, the phenolics are more stable thermally, produce less smoke, have a higher oxygen index, have a lower flame spread rating and produce less toxic gas than the polyester resins. The higher thermal stability and lower smoke release of the phenolics resins relative to the polyester resins is discussed in terms of the degradation mechanism and degradation products of these resins.
