Glass Bubbles
3M(TM) Glass Bubbles S32
3M™ Glass Bubbles S32 have a density of 0.32 g/cc and an isostatic crush strength of 2000 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
