Abstract

Abstract of the Disclosure: A recyclable bumper system based on polypropylene comprises a bumper support A of glass fiber reinforced polypropylene, an energy-absorbing foam core B of foamed polypropylene and a tough shell C
of EP-rubber modified polypropylene which may be coated, and can be recycled by mechanical comminution, extrusion and granulation, resulting in granules from which injection moldings having good mechanical properties can be produced.
