- Lower viscosity, improved flow
- Increased filler loading, reduced cost
- VOC reduction
- Chemical stability and inertness
- Reduced dielectric constant
- Thermal conductivity reduction
- Temperature resistance
3M™ Glass Bubbles S60 glass bubbles have a density of 0.6 g/cc and an isostatic crush strength of 10000 psi. The S Series glass bubbles have smaller particle sizes than the K Series.
