Sensitizers for Emulsion Explosives
Microscopic gas pockets that make detonation reliable at −40 °C.
Hollow glass microspheres are the reference sensitizer for emulsion explosives — stable hot-spots, consistent density, long shelf life in the borehole.
Application scenarios
01
Emulsion explosive sensitization
0.2–0.5 wt% HGM provides reliable initiation and VoD control in bulk and packaged emulsions.
02
Seismic & specialty charges
Precise density and strength windows for shaped and seismic charges.
03
Cold-climate reliability
Glass spheres do not collapse or dissolve — performance at extreme temperatures.
Why switch — on both ledgers
Economic advantages
- Lower sensitizer dosage vs. expanded perlite systems
- Long shelf-life reduces expired-product write-offs
- Bulk emulsion programs: consistent VoD → optimized powder factor
Functional advantages
- Chemically inert in oxidizer matrix
- Narrow size distribution → reproducible hot-spots
- Survives pumping and augering
- No water uptake — emulsion stability preserved
