Product detail
EPS with graphite delivers higher insulation efficiency, enabling thinner constructions and a lower overall footprint in building applications.
CIRCULUM® Grey grades is an expandable polystyrene grade, containing graphite, suitable for the production of light and heavy insulation boards or shape moulding. These grades offer enhanced insulation performance through the addition of graphite during production, which also gives the beads their characteristic grey colour.

CIRCULUM® Grey grades
Circulum® grades are engineered to move through many lifecycles. Produced from expandable polystyrene that becomes 98% air during expansion, the material uses resources efficiently while delivering reliable insulation, protection, and formability. It can be recycled repeatedly and adapted to diverse applications, supporting a circular economy through practical, scalable material behaviour.
