CIRCULUM® Grey grades
When you don’t want to compromise on insulation, our grey grades is where to look. CIRCULUM® Grey grades is an expandable polystyrene grade, containing graphite, suitable for the production of light and heavy insulation block or shape moulding.
These grades offer very effective insulation thanks to graphite, which is added in the production process. This additive also gives these beads their characteristic grey colour. Our grey grades are particularly appreciated in the manufacturing of foamed thermal insulation and packaging.
