Abstract
A white star pyrotechnic illuminant composition, useful in US military M127A1 parachuted hand held signals (HHS), which illuminant provides surprisingly enhanced luminous intensity and luminous efficiency versus the current M127A1 U.S. military HHS white star pyrotechnic illuminant. The inventive illuminant formulation includes a mixture of powdered sodium nitrate, magnesium, alkyl polysulfide polymer and a binder; wherein the magnesium and alkyl polysulfide is preferably recovered from the demilitarization of obsolete munitions to realize a significant savings.
Claims6
A white star pyrotechnic illuminant composition for use in hand held signals, which illuminant provides enhanced luminous intensity and luminous efficiency, comprising:
- powdered sodium nitrate from about 25 to about 35 weight percent,
- recovered magnesium having purity less than 98% mixed with, alkyl polysulfide polymer wherein said mixture is about 63 to about 69 weight percent and wherein the ratio of recycled magnesium to alkyl polysulfide polymer is about 93:7 to about 85:15 percent,
- and a binder at about 3 to about 7 weight percent.
