RECYCLABLE BUMPER SYSTEM

摘要

The invention relates to a polypropylene-based bumper system comprising a bumper support A (1) comprising glass fibre-reinforced polypropylene, an energy-absorbing foam core B (2) comprising foamed polypropylene, and a tough shell C (3) which comprises EP rubber-modified polypropylene and may, if desired, be painted. The bumper system can be recycled by mechanical comminution, extrusion and granulation. The granules can be used to produce injection mouldings having good mechanical properties.
