Current polymers used to bond explosives can be used to make the munition more insensitive to accidental detonation and/or form the material in to a specific shape. The addition of these polymers, however, reduces the energy density. This new innovation using polyphosphazenes improves energetic performance whilst also improving stability.
Although classified as non-explosive, a baseline polyphosphazenes has class-leading energy content. This property, combined with its superior stability, make it ideal for use as an alternative explosive binder — especially if conformance with Insensitive Munitions standards is required. A 15-year research programme conducted by the Atomic Weapons Establishment (AWE) has resulted in a polyphosphazene that gives improved performance and safety.
High Performance — polyphosphazenes used as a replacement explosives binder improves energetic performance.
|.||Reduced Hazard — polyphosphazenes inherent stability results in insensitive/low hazard explosives.|
|.||High Thermal Stability — a high activation temperature provides extended resistance to inadvertent detonation (e.g. exposure to fire).|
The synthetic flexibility of polyphosphazenes and their wide range of unique properties can be potentially utilised in numerous other applications, such as fire-retardant materials.
