GLASS BEADS

SIGMUND LINDNERSiLiBeads

Production

Our glass beads in the 0,05mm and 5mm size ranges, are produced through a special thermal rounding process. The particularity of this way of production is that it need much less energy than other traditional melting processes.

Main Advantages

  • homogenous and smooth surface
  • small proportion of air-bubbles
  • high roundness and elasticity
  • wide assortment of sizes, narrow size-ranges free from foreign particles, glass and other impurities

Applications

Silibeads Type S are optimal for the use as grinding and dispersing media in horizontal and vertical pearl mills for the wet grinding of lacks, pigments, dyestuff, ink, agrochemicals and minerals. As filling agent for chemicals, paper and plastic. The low wear rate of the agitator disc and of the grinding chamber allows to reduce the production costs. The advantage that it brings to the cost-benefit aspect is evident.

Further Applications

Micro glass beads for the surface coating of metal, plastic, ceramic and wood.

  • Filling material for the modification of the physical properties of thermoplast and duroplast.
  • In diameters > 0,8mm as reflection beads for road marking, specially to improve the visibility at night in case of rain.
  • Polishing agent for optical and inter ocular lenses.

For the optimal use of our glass beads, we recommend to carefully follow the instructions for use.
