- Abstract
- The flammability of urethane systems is of broad interest, with practical aspects including intumescent coatings, ablative materials, flexible foams, and especially rigid foams. Numerous papers have appeared giving specific formulations for flame-resistant systems. The thermal decomposition of the polymers, which is an integral part of combustion, has also been studied for several model polyurethanes. This aspect of the subject was reviewed in 1959 and 1962. More recent publications on polyurethanes are reviewed later in this survey. An excellent review of the thermal decomposition of polymers other than urethanes is the book by Madorsky. Certain phases of combustion chemistry have been presented by Dickert and Toone, and an over-all survey has been made by Saunders and Backus. These results in the polyurethane field may be combined with combustion studies in other polymer systems to present an integrated view of decomposition and combustion of broad usefulness. This paper attempts to do that, with particular emphasis on rigid foams.
