3M™ Glass Bubbles help you create powerful, consistent explosive formulations for industrial mining applications.
Moving tons of rock isn't easy. Industrial mining requires the use of explosives that are not just powerful, but also consistent and predictable enough to be controlled. 3M™ Glass Bubbles are hollow glass microspheres that provide a high-strength, low-density sensitizer – enabling the creation of efficient explosive formulations with the stability and power required by demanding mining applications.
Available in a wide range of strengths and densities, 3M glass bubbles are ideal sensitizers for a variety of industrial explosives, including bulk emulsion, packaged emulsion, water gel and slurry explosives.
3M glass bubbles act as pre-manufactured low-density voids, creating "hot spots" within an explosive charge that help increase sensitivity and velocity of detonation (VOD). The greater fragmentation provided by high VOD means:
The high strength and consistent manufacture of 3M glass bubbles provides stable, predictable performance:
