3M™ Glass Bubbles K20, 30 kg

3M™ Glass Bubbles K20 have a density of 0.2 g/cc and an isostatic crush strength of 500 psi.

The K20HS Glass Bubbles can be compounded in a variety of thermoset polymers to reduce the density of the composite. These composites can be incorporated into deep sea syntatctic foam for buoyancy modules to improve the uplift properties of a system at minimal foam volumes. They offer good strength-to density ratio, making them suitable for a variety of applications: buoyancy, coatings, adhesives, sealants, and thermoset resins systems.

• Lower viscosity, improved flow
• Increased filler loading, reduced cost
• VOC reduction
• good strength-to-density ratio
• Reduced dielectric constant
• Temperature resistance
• Chemical stability and inertness
