PERFORMANCE

The EXTENDO® product family is obtained in a multiple-step recycling process from high-performing flat glass as basic raw material. Due to its production process and chemical composition, EXTENDO® provides a series of exceptional properties such as:

  • bright inherent colour
  • excellent hydrolysis & dimensional stability
  • very low absorption of water or oil
  • very good resistance to chemicals, scratches and weathering
  • wide processing window
  • problem-free processing

The performance of Unitika Glass Beads results from the combination of these properties with the spherical particle shape and a particularly fine grain size distribution. In fiber-reinforced compounds of engineering plastics, EXTENDO® increases dimensional stability and reduces shrinkage.

Microglass beads are also used in 3D printing. This includes additive manufacturing processes such as selective laser sintering (SLS).
