High Precision Beads

SiLiBeads® ...high precision

For the past 160 years we have developed and produced high quality glass beads and for the last 15 years we have also used ceramic material.

Our quality management to DIN ISO 9001 has been approved for years.

Precision glass beads are used in technical applications with a high chemical consistency. Contrary to metallic beads, glass beads made from soda lime glass and borosilicate glass are permanently resistant in the pH- area of alkaline as well as acidic solutions:

We recommend SiLiBeads® Glass Beads for the following applications:

  • Valve balls for dosage pumps in the chemical industry
  • Hybrid ball bearings made from plastic and glass for technical rolling- and conveyor appliances in the photo industry
  • Valve balls in aerosols and dispensers in the cosmetics and pharmacy industry
  • Spacers in batteries
  • Valve balls in ink cartridges
