The Shape and Size of The Void Thoroughly Effect Heat Generation. 

The more spherical the void, the higher the internal pressure - temperature upon collapse.

Chemically formed gas voids are not ideally 

spherical or uniform in size.

Time, temperature, and depth alter the shape

and size of chemically gassed voids. As a consequence, detonation performance and

​consistency in the explosives is sacrificed.

Chemical gassing also disrupts the emulsion

phase which diminishes detonation. Worse yet,

gassing can create toxic fumes.

Chemically gassed emulsions are easier and cheaper to make, transport, and store.  However, the loss of performance, safety,

and control is seldom worth the savings.

Emulsion Explosives Require Voids To Detonate.

During the primary phase of detonation,

the voids are rapidly compressed; creating  extremely high temperatures. This causes the emulsion to decompose to a gas state.

Voids are typically applied by chemical

gassing or adding closed celled voids / micro-spheres. We use high strength glass  microspheres.

Microspheres cost a little more, but certainly provide more bang-for-the-buck.Without fail, they offer the best consistency and

superior performance.

Unlike chemical gassing, microspheres are

not effected by time, temperature, or depth.

Microspheres create a more defined

spherical void in the emulsion than the gassed
