By acting as miniature ball bearings to increase flow, SPHERIGLASS solid glass microspheres lower the viscosity of most thermoplastic and thermosetting resin systems during extrusion and injection molding. The sperical shape also provides better stress distribution, reducing the risk of premature failure of parts made from the material. The spheres provide increased strength, dimensional stability, flexural modulus, abrasion resistance, surface hardness, and compressive strength, as well as excellent chemical resistance. They are available in two compositions — A-glass (soda-lime glass) and E-glass (borosilicate glass) — and their cost is less than half that of glass fibers.
