Abstract : This report describes a research effort to develop improved flame agents for high velocity use over a wide temperature range. The basic approach taken was to replace the polystyrene in Napalm B with another polymer in order to improve upon the aerodynamic behavior exhibited by Napalm B. This involved a study of the flow behavior of polymer solutions (viscosity and memory versus shear rate) and their burning characteristics (thermal output and ease of ignition). The memory values obtained can be correlated with the results of air gun tests conducted by the Air Force. Thus, both the elasticity and viscosity must be considered when evaluating solutions for use as a flame agent. The formulations which showed improved flow behavior are Napalm B-type formulations incorporating styrene/butadiene and butylmethacrylate. At room temperature, only slight differences were observed between the burning behavior of styrene/butadiene solutions and Napalm B. Butylmethacrylate solutions did not burn as well as Napalm B. At low temperature, the ignition behavior of the sytrene/butadiene solutions was appreciably better than that of Napalm B. (Author)
