3M™ Glass Bubbles S22

3M™ Glass Bubbles S22 are hollow microspheres made of soda-lime borosilicate glass with a true density of 0.22 g/cm³ and an isostatic crush strength of 400 psi / 28 bar.

Generally, S series Glass Bubbles offer smaller particle sizes than the K series. S22 Glass Bubbles reduce weight and thermal expansion in applications like construction, interior and exterior paints, electronics, and marine coatings.

• Density reduction
• Higher filler loading feasible and lower VOC for paints and coatings
• Thermal conductivity reduction for better thermal insulation
• Chemical stability and inertness
• Reduced dielectric constant
• Temperature resistance
• smaller particle size
