Circulum®

We’re determined to keep innovating in order to lead the change towards a circular economy. A key step in that direction is Circulum®, our EPS grades that require minimal use of raw materials, are 100% recyclable and meet the toughest health and safety requirements in Europe. They’re available with different features which makes them useable in many industries and applications.

Although our Circulum® grades are made from petroleum, they’re both sustainable and circular. The material can be recycled and reused indefinitely and as it’s made from 98% air, it requires little raw material in the first place. From petroleum, we extract liquid monostyrene. That is, in turn, converted into expandable polystyrene, which are small, glass-like spheres that contain the blowing agent pentane. The pentane is steam heated, which causes the spheres to expand (up to 50 times) and become Circulum® pearls. As the pentane escapes the pearls, it is replaced by air. The pearls are then heated with steam and compressed in a mould to merge into a moulded block that can be cut into any shape and form requested.
