The British used a plastic explosive during World War II as a demolition charge. The specific explosive, Composition C, was 88.3% RDX and 11.7% non-oily, non-explosive plasticizer. [8] The material was plastic between 0 and 40 °C (32–104 °F), but was brittle at colder temperatures and gummy at higher temperatures.
Plastic armour replaced the use of concrete slabs which, although expected to provide protection, were prone to cracking and breaking up when struck by armour-piercing bullets. Plastic armour was effective because the very hard particles would deflect bullets which would then lodge between the plastic armour and the steel backing plate.
