You're looking for ways to make vehicles lighter. 3M Glass Bubbles deliver in places you may not expect. These tiny soda-lime-borosilicate glass microspheres are available in a range of densities, compressive strengths and particle sizes. They can replace heavy fillers, such as calcium carbonate, for lightweighting common materials like thermoplastic parts, adhesives, sealants, and composites such as SMC/BMC. What’s more, many grades of 3M Glass Bubbles can survive thermoset, extrusion, injection molding and high-pressure spray application processes – making them excellent for plastisols, structural foams and plastic parts for lighter weight all across the vehicle.
3M Glass Bubbles can also be incorporated into lightweight, thermally insulative fillers for potting resins in EV battery packs. Let’s talk about your lightweighting needs. To determine which grade is best for your application, use the chart below. Or, contact a 3M expert.
