  • using lightweight components, the sound, but also the footfall sound in the room is massively reduced
  • promising application for automotive sector with option of a “Custom Made” type tailored to the needs of end user

Use in construction chemistry


  • use of MagSpheres P- or C-series
  • for everyday products - often made with ceramic balls, glass balls or mineral balls
  • Examples: tile adhesive, precast concrete parts, decorative elements, coatings that reduce electric smog


  • active embodiment in cementitious applications
  • application benefits from ball bearing effect
  • artificially generated radiation that is harmful to health (e.g. smartphone) is reduced
