A truck storage tray, produced from polypropylene (PP) by KraussMaffei using MuCell foaming technology. The foam reduces the density of the part, allowing it to become thicker and stiffer without adding weight. Foaming usually leaves surface marks as a result of the flow of the gas during moulding. It is most visible in black parts. The polymer is modified with additives to reduce the effect and surface texture added to eliminate the visual impact altogether. In this case, a textured in-mould label (IML) has been added to the centre (silver), completely concealing the black plastic beneath.

Cross-section through a reusable foamed cup in polypropylene (PP), manufactured using EcoCore injection moulding technology, that integrates an insulating foam between the two outer skins (MuCell microcellular foam injection). The graphics are applied using a PP in-mould label (IML), which ensures the returnable cup remains recyclable as a monomaterial at the end of its life.

Renault interior door panel made with LYB LyondelBasell polypropylene (PP) with a chemical foaming agent added to produce a foamed part. This approach helps to save 15-20% weight. The texture is designed to eliminate the need for a covering, to save cost and ensure the part can be recycled end of life.
