| 3M™ Glass Bubbles S32HS are high-strength, low-density additives specially formulated to afford greater survivability than other lightweight additives under demanding processing conditions. 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. 3M glass bubbles help to reduce weight; reduce noise, vibration and harmonics; reduce thermal expansion; and contribute to cost savings. They are used in a variety of applications in diverse markets, including automotive, construction materials, electronics, marine and paints and coatings.Information provided by 3M |
