Polyamides (PA) are macromolecules characterized by the CO-NH amide group, on which many properties of this type of compounds depend.

Polyamides can be synthesized by condensation polymerization of a dicarboxylic acid and a diamine or by ring-opening polymerization of a lactam.

The characteristics of the individual types of polyamide do not differ much: relatively low specific weight, impact and wear resistance, fair electrical insulation, resistance to solvents, oils, greases and fuels. Self-extinguishing, they have a high moisture absorption, so they are not suitable in contact with water or when demanding tolerances are to be maintained.
