Novel Plasticizer for IM Compliant Solid Propellants

摘要

NITROFURAZAN PLASTICIZERS (NF): Nitrofurazan family offers promise as high energy, good thermal behavior, high density and low sensitivity plasticizers. * NF core: heterocyclic ring with high thermal stability, good density * Organic Group R: capability to functionalize the nitrofurazanic core * R group variation may generate various categories of NF plasticizers. CONCLUSIONS: NF2 has been successfully synthesized and characterized in a 40% overall yield * NF2 synthesis used low cost precursors and was produced in high purity (>98%) * NF2 Testing Results: insensitive ('green' category material) * NF2 showed good thermal properties: it has good decomposition temperature and low volatility * Additional work will be conducted - NF2 will be incorporated in propellant samples (work in progress at Aerojet).
