Product Details

3M™ Glass Bubbles K20HS are hollow microspheres made of soda-lime borosilicate glass with a true density of 0.20 g/cm³ and an isostatic crush strength of 750 psi / 52 bar.

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.
