(cid:1)
Dinitrotoluene (DNT) has been used for years as energetic
plasticizer in many propellants – DNT, however, is
extremely toxic.
(cid:1)
Current Stabilizers are either very toxic by themselves
or they produce toxic products during ageing.
(cid:1)
Nitroglycerine NG has physiological effects in
cardiovascular system. nitroglycerine has migration
tendency.
(cid:1)
Phthalate-Plasticizers (DBP) is toxic.

The Task:
Development of a high performance LOVA propulsion systems
for gun ammunitions
Desired Features:
• Extended range.
• Raising Energy contents by using high impetus formulations.
• Increase progressivity.
• Low temperature dependency.
• Controllable burning rate regime.
• Improved safety and toxicity properties.
• Green ingredients as much as possible.
