3M™ Glass Bubbles S15

Glass Bubbles
3M(TM) Glass Bubbles S15
Because of their high strength-to-weight ratio and spherical shape, S15 glass bubbles are used by formulators to increase filler loading, lower viscosity, reduce shrinkage, reduce warping and increase buoyancy.
  • Lower viscosity, improved flow
  • Increased filler loading, reduced cost
  • VOC reduction
  • Chemical stability and inertness
  • Reduced dielectric constant
  • Thermal conductivity reduction
  • Temperature resistance
