. Fluoropolymers may be mechanically characterized as thermosets or thermoplastic
Thermoplastic

A thermoplastic is a polymer that turns to a liquid when heated and freezes to a very glassy state when cooled sufficiently. Most thermoplastics are high-molecular mass polymers whose Chain s associate through weak Van der Waals forces ; stronger dipole interactions and hydrogen bonding ; or even stacking of aromatic rings ....
s. They are often applied to manufactured metal parts by electrostatic powder coating
Powder coating

Powder coating is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form....
