Novum Glass Solid Soda-lime Uniform Series Glass Microspheres
Categories:	Ceramic; Glass; Oxide; Silicon Oxide
Material Notes:	Solid soda-lime glass microspheres in colorless powder form. Uniform Series Microspheres are used for controlling a bond line thickness in adhesive bonding. Solid glass microspheres are used in a variety of industries for maintaining a consistent space between objects, allowing for more repeatable results and fewer rejected parts. U-Series microspheres can be used for calibration where a NIST traceable size standard or identical particles are required. Information provided by Novum Glass, LLC.
