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.

Recyclable bumper system

A fuel tank made of a thermoplastic, having a splash baffle formed by two ridge-like protrusions (2, 8) molded from mutually opposite tank walls (3, 4), which protrusions touch and are joined to one another at the points of contact (5) (and which tank may or may not possess a device for hindering fuel outflow), wherein the wall of the splash baffle has openings (6) which provide a connection between the tank space and the splash baffle over a threshold (9) which favors retention of fuel within the baffle.
