Expansion technology

The BUBLON-Technology sets new standards ...
 
... in the technology itself:

  • product characteristics can be specifically adjusted
  • minimum energy consumption
  • emission-free

... in product quality:

  • BUBLON® Spheres with glazed and closed surface
  • high mechanical strength, definable density,  non-hygroscopic
  • for diverse, innovative applications in the industry

... economically and environmentally:

  • use of purely natural and inexpensive and sustainable raw materials
  • direct energy transfer through radiation heat only
  • 100 % recycling of the expanded perlite into the eco-cycle

With Bublon’s innovative expansion technology, naturally occurring raw materials are expanded to up to 20 times their original volume by heating them up to more than 800°C.
The resulting purely natural and functional lightweight fillers are characterized by their glazed and closed sur-face; they are barely dusty, non-hygroscopic and also offer a high mechanical strength.
The innovative BUBLON® Spheres are ideally suited for the production of insulation and fire protection boards, renderings and plasters, as a natural, ecological filler for the plastics industry, as an additive in paints and var-nishes or as a substitute for microplastics. Consequently, they are also used as an inexpensive, ecological alternative to conventional microspheres and as a very stable substitute for cenospheres in terms of price and supply.

The Bublon technology

Expanded industrial minerals

CONVENTIONAL TECHNOLOGY

Conventionally expanded Perlites are characterized by: 

  • pronounced hygroscopic properties
  • little dimensional stability and low mechanical strength
  • limited uses in the construction and insulants industries

BUBLON EXPANSION TECHNOLOGY

BUBLON® Spheres have a glazed and closed surface, resulting in 

  • little dust
  • little water absorption
  • high mechanical strength
  • optimally suited for the production of boards, plaster and moulded products

Expansion technology

CONVENTIONAL TECHNOLOGY

  • Bulk densities 40–120kg/m3
  • open cell surface
  • means
  •  very hygroscopic
  • low mechanical strength
  • very dusty at handling
  • energy and waste gas-intensive

BUBLON EXPANSION TECHNOLOGY

Bulk densities 80–600kg/m3
glazed and closed cell surface
means

  • little water absorption
  • high mechanical strength
  • very low dust at handling
  • less energy consumption and waste gas-free
