A realistic acceptance specification for benite strands was prepared. Conventional Ordnance manufacturing equipment may be used. Technical grade potassium nitrate is satisfactory. Increasing the drying temperature to 131 F reduces drying time from 10 days to 12 hours. Reworkng doubles the yield. Stability is improved by substituting diphenylamine for ethyl centralite. Processing characteristics are improved by the use of ethyl acetate and alcohol as solvents instead of diethyl ether and alcohol. Multipleorifice plates for extrusion and dowels for drying of the strands are recommended for high capacity production equipment. Benite colloid does not detonate under severe conditions of confinement it is accordingly considered a Class 2 explosive hazard fire hazard for extrusion. The performance characteristics of benite are relatively insensitive to minor changes in formula and dimensions.
