XPT (eXplosion Protection Technology) can most simply be described a 'stone sponge'. Its inherent porosity allows the blast shockwave to enter its structure. There, thousands of small air chambers slow the blast wave down, trapping it and then making it expend it itself by breaking up the structure of the XPT.
There are a number of different stages in the breakdown of XPT and it takes a very severe blast loading to get through all of them. Each stage, through its specific mechanism, takes more energy out the blast, protecting the structure or object behind it and also reducing the energy reflected off it.
XPT is a practical engineering material. Panels or mouldings can be cast into many shapes, requiring only simple and inexpensive mould tools. It has excellent fire resistance, reduces ambient noise and helps in the retardation of the fragments often generated in an explosion.
