| 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 ideal for plastic and rubber parts created from injection molding, extrusion processes and/or other vigorous processing equipment (Banbury mixers, etc.). Scotchlite glass bubbles help to reduce weight; reduce thermal expansion; and contribute to cost savings. They are used as additive materials in the automotive, truck, rail and aerospace industries.
