BUBLON® Spheres

Unique. Today's light-weight filler for tomorrow.


Different granulates with one technology.

The BUBLON-Technology allows the expansion of spheres with different grain sizes and adjustable bulk density  resulting in a broad range of possible applications.

BUBLON® Spheres are setting new standards:


  • vitrified and closed surface
  • high mechanical strength
  • incombustible
  • high abrasion resistance
  • low dust levels
  • no water absorption
  • excellent insulating characteristics
  • reduced weight
  • reduced cycle time
  • optimized wall thickness
  • improved compressive and tensile strength
  • cost reduction
  • low environmental impact
