Glass Bubbles
3M(TM) Glass Bubbles A20/1000
A20/1000 glass bubbles have a density of 0.2 g/cc and an isostatic crush strength of 1000 psi. They have less than 1% sinkers by volume and are surface treated with methacrylato chromic chloride.
  • Lower viscosity, improved flow
  • Increased filler loading, reduced cost
  • VOC reduction
  • Chemical stability and inertness
  • Reduced dielectric constant
  • Thermal conductivity reduction
  • Temperature resistance
