Soda-lime balls are recommended for applications requiring hardness and excellent resistance to corrosion. In applications where high temperatures and sudden temperature changes are expected, borosilicate glass is recommended for its additional resistance to chemical corrosion and temperature fluctuation. Glass Balls can be made in the same diameter and tolerances as stainless steel balls, in smooth, matte, and polished finishes.
Glass microspheres, also known as decorative glass beads, have been used for at least 100 years. In 1922 large quantities of high refractive-index glass beads were produced to coat movie screens. Since that time, many industries started to rely on solid and hollow glass microspheres as a major component in their products and processes. Initially used primarily as a filler for plastics in the 1960s, glass microspheres found applications in in many industries and thousands of applications including aerospace and military materials, molded plastic components, retroreflective highway signs, oil and gas, recreation, paints and coatings, transportation, construction, mining explosives, personal care, cosmetics and consumer products. In recent years, glass microspheres have become popular due to the availability of high quality glass microspheres with perfectly sphericity, tight tolerances and particle size distributions available on the market. These industries include biomedical, life sciences, microscopy, automotive, high-tech equipment and specialty applications. Solid glass microspheres, spheres, and beads offer an inert high-strength precision particle for use as reference, calibration and spacer applications. They act as mini-magnifying glasses to deliver visually truer colours and can clarify and magnify the visual impact of pigments and metallic flakes, creating a richer, wetter, and deeper look in paint and coatings.
