Solid Glass Microspheres, also called glass beads, provide multiple benefits including enhanced processing, excellent chemical and heat resistance, thermal stability, low oil absorption, and are used in automotive, electrical, household appliance, adhesives, packaging, paint and construction industries. Glass is non-toxic, extremely stable and recyclable.

Compared to other microspheres, such as plastic or hollow glass, solid glass spheres have a high density of about 2.2g/cc for borosilicate glass spheres, 2.5g/cc for soda lime glass spheres, and 4.49g/cc for barium titanate glass spheres. Solid glass spheres have high crush strength which makes them suitable for high stress applications where microspheres are exposed to a lot of stress during processing or application. There are many advantages to using glass microspheres:

  • Solid glass microbeads act as mini-magnifying glasses to deliver visually truer color
  • Clarify and magnify the visual impact of pigments and metallic flakes
  • Create a richer, wetter, deeper look
  • Visually extend expensive color-shift pigments to create cost-effective new looks
  • Facilitate even dispersion of colorants and reflectors
  • Act as mini-ball bearings to improve material flow and reduce flow lines
  • Provide color consistency from all viewing angles
  • Impart durability and chip resistance due to hardness of glass
  • Offer a durable non-deformable spacer particles for bond line applications
