CIRCULUM® Flame retardant grades

EPS with flame-retardant properties for stable, compliant performance.

Overview

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.

Flame retardant EPS

A material built to circulate

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.
