Abstract: The invention relates to the use of a composition as an extrusion agent for the production of an extruded product, wherein: the extruded product comprises a polyolefin, as well as fillers in a concentration greater than or equal to 15% by weight; the composition used comprising a fluorinated polymer having a viscosity less than or equal to 15 kP at a temperature of 232° C. and at a shear rate of 100 s−1. The invention also relates to an extrusion method for a polyolefin supplemented with fillers, in the presence of such an extrusion agent.
