| 3M™ Glass Bubbles K42HS are high-strength polymer additives made from a water-resistant and chemically-stable soda-lime-borosilicate glass. These hollow glass microspheres can be used as a low-density filler material that is ideal for plastic and rubber parts created from injection molding, extrusion processes and/or other vigorous processing equipment. 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™ |
