3M™ Glass Bubbles S28HS are high strength hollow microspheres made of soda-lime borosilicate glass with a true density of 0.28 g/cm³ and an isostatic crush strength of 3000 psi / 210 bar.
The S28HS Glass Bubbles offer a very good strength-to-density ratio and small particle size, making them suitable for a variety of applications such as buoyancy in oil and gas, airless sprayable paints and coatings, adhesives, mastics, sealants, SMC and other thermoset resin systems.
