CIRCULUM® Flame retardant grades

These grades are designed to ward off fire. Usually, insulation materials in walls and floors are easily flammable. By adding our flame retardant EPS to your insulation, you also boost fire protection.
The benefits of our flame retardant grades reach further, as the insulation properties of these grades also increases the level of insulation. 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. They can be shape moulded and block moulded as you require.
