Void-Free Flame Retardant Phenolic Networks: Properties and Processability
… composite industry because of their excellent flame retardance and cost effectiveness. However, the common procedure for curing phenolic novolac resins uses hexamethylenetetramine (HMTA) and releases volatiles during the cure, which produce networks with numerous voids. This results in …

Cresol Novolac/Epoxy Networks: Synthesis, Properties, and Processability
… properties while maintaining excellent flame retardance. A series of linear, controlled molecular weight, 2,6-dimethylphenol endcapped cresol novolac resins have been synthesized and characterized. The molecular weight control was achieved by adjusting the stoichiometric ratio of cresol …

Modification, curing and flame retardation of epoxy resin networks
… poly(arylene ether sulfone)s and improved flame retardance of di- and higher functionality epoxy resins were investigated. The influence of curing temperature and time on morphological development and fracture behavior was also studied. Arylamine functionalized poly(arylene ether sulfone)s …

Characterisation of Halogen Free Fire Retardant Polypropylene Composites Reinforced by Short Natural Fibres
… drawback of currently available filler type flame retardants is that, they require considerably large amount of filler (by weight) to achieve the standard flammability ratings and thereby promote adverse effects on the mechanical properties of the composites. Use of intumescent ammonium …
