Flammability properties and mechanical performance of epoxy modified phenolic foams

摘要: This work has been mainly focused on the development and optimization of processing methodology to produce epoxy modified phenolic foams. study analyzes relation between composition structure as well mechanical flammability performance epoxy-phenolic (E-P)-based Phenolic foams with different types compositions resin were successfully synthesized characterized, showing uniform pore structure. Two resins used for this approach. One is regular diglycidyl ether bisphenol A (Epon 826) type other a brominated (DER 542), which halogen groups in improve properties resulting Cone calorimeter (ASTM E 1354) was measure heat release rate, time ignition, E-P resins, under well-controlled combustion conditions. The system studied compared competing foams, such us phenolic, epoxy, polyurethanes, aspects compression, friability, shear performances. Compared conventional exhibit significant improvement performance, lower friability similar resistance flame. These results demonstrate potential foam flame resistant high core material sandwich © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 1399–1407,
