Solid Glass Particles

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
CATEGORIES
Solid soda lime glass, also know as soda lime silicate glass, is the most common type of solid glass microspheres available. These particles are offered in a wide selection of sizes and grades (precision, classified, bulk and spacer) with coated and uncoated options.
Borosilicate glass is well-known for its durability, low coefficient of expansion, low density, high softening point, high resistance to acids and thermal shock, compared to other glass formulations. The microsphere choice for demanding corrosive environments.
Barium titanate glass spheres offer a higher Refractive Index [RI] than most other glass formulations. Depending on the grade of material reflecting index of barium titanate glass is from 1.9 to 2.2 compared to ~1.5 of soda lime and borosilicate glasses. Barium titanate glass microspheres will reflect back more light directly to the viewer.
A fluorescent coating is applied to half of each microsphere, making the glass particles appear colorful, fluorescent, and highly visible in daylight. Coated glass microspheres exhibit bright fluorescent response under ultraviolet (UV) light enabling these particles to function spectacularly as fluorescent high visibility tracers.
