Abstract
Structural support (1) including a first support portion (2) delimiting at least one containment compartment (4, 4′); a second support portion (6) at least partly in front of the containment compartment (4, 4′); and a sliding element (4), housed in the containment compartment (4, 4′) and interposed between the first (2) and the second (6) support portion. The sliding element (8) substantially consists of a thermo-processable fluoro-polymer with a melt-mass flow rate—according to the ISO 1133-1:2011 standard—of less than 5.0 grams/10 minutes, for example under 3.0 grams/10 minutes.

Structural support comprising:
- a first support portion delimiting at least one containment compartment;
- a second support portion at least partly in front of the containment compartment;
- at least one sliding element, partly housed in the containment compartment and interposed between the first support portion and the second support portion;
- wherein the sliding element substantially consists of a thermo-processable fluoro-polymer with a melt-mass flow rate (MFR)—according to the ISO 1133-1:2011 standard—of less than 5.0 grams/10 minutes, and
- wherein the thermo-processable fluoro-polymer consists of one or more tetrafluoroethylene (TFE) copolymers, where the percentage by weight of TFE in the TFE copolymer is less than 98%.
