3M(TM) GLASS BUBBLES K42HS

3M™ Glass Bubbles K42HS are high-strength polymer additives made from a water-resistant and chemically stable soda-limeborosilicate 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.
