Ranges of Application

S 4000® is used as thermal insulating board or as mechanical part for heated presses and tools in the plastics-, rubber– and wood processing industry.

Special material characteristics

  • long-term temperature resistance
  • exceptionally good insulation effect combined with
       high compressive strength
  • good chemical resistance against acids and solvents


S 4000® offers significant advantages compared to inorganic brittle insulation materials. In comparison to other glass fibre reinforced insulation materials S 4000® offers the same insulation effect with distinctly lowered insulation thickness.
