Explosion proof fuel tank foam
Fuel tank is one of the most vulnerable parts in armored vehicles and aircraft. In a fuel tank , the empty space above the fuel level contains an explosive mixture of fuel vapor and air. Any gunfire or penetrated fragmentation will ignite vapors around it and create and ever-growing compression wave to compress the un-ignited vapor in a chain reaction, which finally leads to a fatal and catastrophic explosion within milliseconds.
FuegardTM explosion-proof foam can virtually eliminate such catastrophic explosion and drastically increase the survivability if armored vehicle and aircaft. It is flexible network structured polyurethane foam with fully open pores,composed of pentagon and dodecahedron skeletal network of tiny lightweight interconnecting strands, which act as 3D fire screen. The foam confines the vapor ignition to the area around the ignition source and prevents the chain reaction from occurring .Flame and wave propagation are mitigated by the foam to below propagation levels.
