Regular EPP

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

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

KEY BENEFITS

100% Recyclable Thermal Insulation Strength Lightweight Impact Absorption

Sound Deadening
