Abstract : This report describes a research effort to develop improved flame agents for high velocity over a wide temperature range. The approach taken was to replace the polystyrene in the present Napalm B with another polymer or blend of polymers in order to improve the aerodynamic behavior. This involved a study of the flow behavior of polymer solutions (viscosity and elasticity versus shear rate). The elastic values obtained were correlated with results of air gun tests. Thus, both elasticity and viscosity must be considered when evaluation solutions for use as flame agents. The formulations which showed improved flow behavior were various blends and rations of styrene-butadiene solutions ranging from 27 to 30 percent rubber in gasoline and benzene with the ratio of blending from 1:4 to 4:1 styrene-butadiene rubber (SBR) 43/40.
