ATMIS Normal EPP

Expanded Polypropylene (EPP) is a highly versatile closed-cell bead foam that provides a unique range of properties.

ATMIS-EPP can be made in a wide range of densities, from 15 to 200 g/l, which are transformed by moulding into densities ranging from 18 to 260 g/l. Individual beads are fused into final product form by the steamchest moulding process resulting in a strong and lightweight shape.
