Product details
EPS with flame-retardant properties for stable, compliant performance.
Our flame-retardant grades offer added benefits beyond fire safety, combining protection with effective insulation performance. We produce flame retardant beads in sizes ranging from 0.5 mm to 2 mm, which covers all applications from thin-walled and detailed products to light insulation boards.

CIRCULUM® Flame retardant 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.

Versatile white EPS grades developed for efficient processing and reliable results in packaging, shape moulding and insulation, where consistency and performance matter every day.
Flame-retardant grades improve fire performance by reducing ignitability. They are mainly used in building insulation and other applications with stricter fire-safety requirements.
Graphite-enhanced EPS, including flame-retardant options. Delivers higher insulation efficiency, enabling thinner constructions, reduced material use and a lower overall footprint in building applications.
EPS raw material made from recycled content - for a lower carbon footprint and reduced reliance on virgin fossil materials.
When standard EPS is not sufficient, we offer EPS grades with properties designed for specific purposes.
Certified Balanced lowers carbon footprint while maintaining premium EPS performance, ideal for food, pharma and other applications where recycled content is not yet viable.
Derived from biopolymers developed from organic materials, BioFoam® can be used for several purposes and even made into soil.
