3M™ Glass Bubbles for Transportation

  • From highways to the airways, off-road and on the water – everywhere you go, 3M helps you get there, with smarter, more efficient vehicles. In an industry where every ounce counts, lightweighting with 3M™ Glass Bubbles can shed pounds per vehicle. Lighter weight vehicles are more fuel efficient. On a small scale, that means filling up at the pump less often. Across an entire fleet, manufacturers can more easily meet weight reduction targets and emissions standards.

    These high-strength, low-density hollow glass microspheres enable weight reductions of up to 15% or more in many plastics, thermosets, structural foams and sheet- and bulk-molded composites, all while maintaining desirable physical properties – including the ability to deliver a Class A surface finish.

  • Automotive and Commercial Vehicles

    3M glass bubbles can be used in a variety of interior and exterior automotive and commercial vehicle applications, from pillar trim and central consoles to the hood, fenders, tire tubs and much more. Other applications include autobody filler, lightweight seam sealer and underbody coatings.

  • Aircraft

    Interior cabin components filled with 3M glass bubbles can potentially save several pounds per aircraft. Extended to an entire fleet over a 15-year operating life, this can translate to significant total fuel savings, in addition to important reductions in carbon emissions.

  • Recreational and Marine Vehicles

    3M glass bubbles can help reduce the weight of sheet molded and injection molded components in watercraft and other recreational vehicles, helping reduce fuel consumption. Potential applications include jetskis, boats, ATVs, motorcycles, snowmobiles and more. 3M glass bubbles can also help reduce shrinkage and warpage in lightweight marine putties.
