Article made from a heavy plastic material

An article made from a material having a density between 2 and 7 g/cm3, the material comprising by weight for a total of 100%:

• a filler (2) made from a metal and/or ceramic material having a density greater than or equal to 3 g/cm3, said filler (2) being present in a percentage greater than 50% and less than or equal to 85%,
• at least one polymer (4) present in a percentage greater than or equal to 15% and less than or equal to 50%,
• at least one coupling agent (3) present in a percentage greater than or equal to 0% and less than 10%,
• at least one reinforcement present in a percentage between 0 and 10%,
• at least one pigment present in a percentage between 0 and 5%,
• at least one diluent and/or a plasticiser present in a percentage between 0 and 5%,
• said polymer (4) being bonded to the filler (2) and/or, when the material comprises at least one coupling agent (3), the coupling agent (3) being respectively bonded to the polymer (4) and to the filler (2) by one or more bonds chosen from a hydrogen bond, a coordinate bond and an ionic bond.
