Ballistic foam | Revolvy

Ballistic foam Ballistic foam is a foam that sets hard. It is widely used in the manufacture and repair of aircraft to form a light but strong filler for aircraft wings. The foam is used to surround aircraft fuel tanks to reduce the chance of fires caused by the penetration of incendiary projectiles.[1] Ballistic foam is a type of polyurethane foam placed in the dry bays of aircraft.
