Method for manufacturing a plastic web for the production of a trim panel

A method for manufacturing a plastic web comprising:

• a step of hot extrusion of thermoplastic particles;
• the thermoplastic particles comprising polyolefin particles, the polyolefin particles being selected from:
• thermoplastic polyolefin (TPO) particles;
• thermoplastic vulcanized polyolefin (TPV) particles;
• thermoplastic elastomer polyolefin (TPE) particles;
• and a mixture of all or some of these particles;
• a quantity of polyolefin particles being between 50% and 96% by weight, relative to a total weight of thermoplastic particles,
• the polyolefin particles being at least partially derived from recycled materials,
• the method being characterized in that:
• in a case where the polyolefin particles comprise thermoplastic polyolefin (TPO) particles, a melt flow index (MFI) of the thermoplastic polyolefin particles is between 0.3 g and 10 g/10 min;
• in a case where the polyolefin particles comprise thermoplastic vulcanized polyolefin (TPV) particles, the melt flow index (MFI) of the thermoplastic vulcanized particles is between 10 g and 30 g/10 min;
• and
• in a case where the polyolefin particles comprise thermoplastic elastomer polyolefin (TPE) particles, a hardness of the thermoplastic elastomer polyolefin particles is between 45 and 65 Shore A.
