    • 3M Glass Bubble Microspheres

      Imagine the lightest of particles helping to reduce the weight of the airplanes we travel in and the cars we drive giving us better overall fuel economy. At 3M, our glass bubbles do that every day. With a high strength-to-weight ratio, this technology is essential in lightweighting materials like plastics and composites. Across industries, our glass bubbles are also used as filler alternatives that can reduce total systems cost while providing enhanced product properties.
