A polymer-bonded explosive, also called PBX or plastic-bonded explosive, is an explosive material in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer ("plastic").
PBXes are normally used for explosive materials which are not easily meltable to cast or which are otherwise hard to form.
Polymer-bonded explosives have several potential advantages:
- If the polymer matrix is an elastomer (rubbery material), it tends to absorb shocks, making the PBX very insensitive to accidental detonation.
- Hard polymers can produce PBX that is very rigid and maintains a precise engineering shape even under severe stress.
- PBX powders can be pressed into a particular shape at room temperature, when casting normally requires hazardous melting of the explosive. High pressure pressing can achieve density for the material very close to the theoretical crystal density of the base explosive material.
- Many PBXes are safe to machine — to turn solid blocks into complex three-dimensional shapes. This technique is used at nuclear weapons fabrication plants.
