A variety of different types of polyamides can be distinguished. For technical applications, PA6, PA66 and PA12 are the most important polyamide materials. Apart from the standard qualities, there exist a multitude of polyamides that are customized by means of additives, to suit the requirements of particular applications.
Semi – finished parts can be fabricated in a monomer casting process or an extrusion process. Polyamides produced in the monomer casting process show a higher degree of crystallinity and have therefore considerably better material properties than extruded types.
Along with type specific properties, all polyamides share a large number of main properties that are specific to the material.
These properties are:
High mechanical strength, hardness, stiffness
High mechanical damping capacity
Good fatigue resistance
Very high wear resistance
Good sliding and emergency running properties
Good machinability
