POC Receptor Backcountry ski helmet featuring high gloss injection moulded polycarbonate alloy (PC/ABS) outer shell, combined with an inner layer of PC/PTFE. The two shells are designed to rotate separately during a crash to lessen the effect of oblique impacts on the head. The outer shell is co-moulded with an impact resistant expanded polypropylene (EPP) inner layer.
Expanded polypropylene (EPP) over-moulded with polyurethane resin (PUR). This type of direct coating, using a rubber-like PUR with texture, is used to create tactile surfaces for automotive interiors.
Expanded polypropylene (EPP) moulded into an injection moulded PP shell. The rigid PP outer provides a visual surface that protects the EPP from indentation and provides additional rigidity.
Looking inside a typical sun visor, which contains an injection moulded PC/ABS structure, and the cavity is filled with moulded expanded polypropylene (EPP), which provides a durable and lightweight body.
