SiLiBeads® Type P

Precision glass beads Type P as valve ball, mixing beads, locking ball, for ball bearings.
Type P glass beads are made of soda-lime glass and high-quality borosilicate glass. SiLibeads glass beads Type P achieve highest precision through a special grinding process. The diameter and roundness tolerance is < 10 microns on request. The manufacturing process allows all special dimensions in the range between 0.7 and 50 mm.
The surface quality of the glass beads can be selected from high-gloss to frosted, borosilicate glass and solid-coloured coloured glass beads can also be produced on request.

The chemical resistance allows the use in aggressive and corrosive media.<br>

Valve ball – Closure beads
The glass beads are used as valve beads for ink cartridges and dispensers in the food and cosmetics industry. Metering pumps are often equipped with Type P glass beads.<br>

Ball Bearings
Glass beads are used in ball bearings where corrosion resistance and chemical resistance play a role.<br>

Mixing Beads
The pharmaceutical industry is a large field of application for mixing beads. For example, insulin carpules contain a borosilicate glass ball, which mixes the contents by shaking to achieve an even mixture of insulin.

  • exact and freely selectable diameters in the size range d = 0.7 – 50 mm.
  • small diameter tolerances for both single beads dK ≤ 20 µm and lots dL ≤ 20 µm.
  • high shape retention and roundness dMAX – dMIN ≤ 20 µm.
  • homogeneous surfaces with defined roughness, matt, silk matt and (highly) polished, with Ra ≤ 30 nm.
  • no adhesions and inclusions.
  • No air bubbles dB ≥ 0.5 mm, very low percentage of beads with air bubbles dB≤ 0.5 mm.
  • Suitable for contact with foodstuffs possible.
