K37 glass bubbles have a density of 0.37 g/cc and an isostatic crush strength of 3000 psi. The general purpose K Series glass bubbles are the most economical 3M glass bubbles.
Application Guide
Listed below are key applications for K37 glass bubbles. Documents specific to the application are listed to the right.
Industrial Explosives
The strongest 3M glass bubble used in mining applications, K37 glass bubbles are ideal for use in the most difficult conditions. Their extremely high strength protects them from dead pressing and their low-density provides outstanding velocity of detonation (VOD).
High fragmentation
Inert, non-coalescing particles provide consistent performance over time
True density: 0.37 g/cc
Target crush strength (90% survival): 3000 psi
Paints and Coatings
3M Glass Bubbles offer a variety of benefits to light weight, high-build elastomeric roof coatings, anti-condensation coatings, etc. Here are some of the benefits:
