Advantages:  Hollow glass bubbles/microspheres have characteristics as light weight, high strength, good fallibility, low oil absorption, steady physical and chemical properties. It can improve the detonation property and storage stability of emulsion explosives if add hollow glass bubbles as density conditioning agent.  Hollow glass bubbles/microspheres were adopted as density conditioning agent in the developed countries long time before.


a.Effective density conditioning agent

The true density of hollow glass microspheres is very low, the density of emulsion explosives will be changed only adding 3wt.--6wt.%. 


b.Excellent sensitizer

Tiny and steady bubble space will become when hollow glass bubbles distribute evenly in emulsion explosives. Each sphere will become a scorching point to the performance of the detonation. Low oil absorption, particle size makes hollow glass bubbles suitable as emulsion explosive sensitizer.


c.Good stabilizer
