Product details
Standard EPS grades designed for predictable, efficient performance.
Combined into boxes, these beads keep salmon fresh from the sea to the dinner table and ensures that critical vaccines arrive safely at their destination. Through block moulding, our standard grades help provide reliable insulation for comfortable indoor climates. With strong insulation performance, consistent quality, and excellent moulding properties, our standard grades are suited for a wide range of applications.

CIRCULUM® Standard grades
Circulum® Standard grades are engineered to move through many lifecycles. Produced from expandable polystyrene that becomes 98% air during expansion, the material is resource efficient while delivering reliable insulation, protection, and formability. It can be recycled repeatedly and adapted to a wide range of applications, supporting a circular economy through practical and scalable material behaviour.
