New 3M™ Glass Bubbles K15HSN: High Strength, Low Density Performance

3M GLASS BUBBLES K 15 HSN are high strength, low-density additives specially formulated to potentially afford higher survivability at low resin densities. They are hollow glass microspheres made from water-resistant and chemically-stable soda lime borosilicate glass. These hollow glass microspheres can be used as a low-density filler material for many applications. They help reduce density and offer improved thermal insulation for better energy efficiency. They are used in a variety of applications in diverse markets, including automotive, construction, paints and coatings, and oil and gas applications.
