Glass beads with the diameter of 710 microns and smaller ones should be used as granular filter in plastic. To create the bond between the plastic and glass beads compound, they normally use 2 main active substance groups as Silane and Maleic Anhydric. Glass beads should be easily dispersed in the Polypropylene plastic compound and they have following advantages:

  • Increasing the protection against abrasion, scratching by the smooth surface and hardness of the glass beads.
  • Increasing impact resistance by the thermal stress of the glass beads
  • Keeping the size of plastic stability and improving its features

The normal size of the glass beads used to mix in the plastic is under 710 microns. However, different plastic products would require different bead sizes.
