3M™ Glass Bubbles S22

Glass Bubbles
Glass Bubbles
S22 glass bubbles have a density of 0.22 g/cc and an isostatic crush strength of 400 psi. The S Series glass bubbles have smaller particle sizes than the K Series.
  • Lower viscosity, improved flow
  • Increased filler loading, reduced cost
  • VOC reduction
  • Chemical stability and inertness
  • Reduced dielectric constant
  • Thermal conductivity reduction
  • Temperature resistance
