sh_cenospheres PCS-U are spherical shaped aluminosilicate hollow balls that are characterized by low-dust, high pressure stability and balanced density. They are easy to disperse and generate bearingball-effects.


  • Balanced real density (approx. 0,7 g/cm<sup>3</sup>)
  • Pressure stable
  • Spheric shape
  • Free-flowing
  • Inert
  • Frostproof
  • Temperatur-resistant
  • Resistant to thermic shocks
  • Resistant to chemicals
  • Free of odour
  • Incombustible
  • Dimensionally stable

Typical Applications

  • Light filling compounds
  • Lightweight plaster
  • Construction chemicals
  • DispersionsProducts made of polyester-, epoxid-, phenolic resin and polyurethane
  • Light- SMC und -BMC
  • Glass fiber (GRP)
  • Underseal and PVC-plastisoles
  • Structural colours and structured plasters
  • Mortar
  • Self-levelling screed
  • Heat insulation coating
  • Artifical marble
  • Anti-drumming mass
  • Refractory materials
  • Adhesives
  • Sandwich-panels

Your benefits

  • Pressure-stability, also in case of higher shear forces
  • Low water absorption
  • Reducement of density and hence weight savings of end products
  • Improvement of profitability due to reduction of the need for binders and resins
  • Higher productiveness of end products (layer thickness per surface)
  • Good flow characteristcs
  • Higher input of fillers
  • Improved head and noise protection
  • Reduced shrinking
  • Improved results of flexural strengths and impact strenghts
  • Increased resistance to chemicals
  • Increase of packing densities and bonding strenghts
