Method for producing a float, fuel-resistant float and use of particles compressed together, obtained by extrusion

摘要

The invention concerns a float (2) sensing a motor vehicle fuel tank level, comprising a plurality of plastic particles (7, 8) compressed together and foamed by extrusion in a free space. Said particles comprise a very large proportion of inclusions (9, 10) of pore-forming agent with respect to the plastic material thereby having a particularly reduced specific weight. The float (2) can consequently be produced from particularly economical plastic material.
