Polyamide
Polyamide 66 or Nylon 66 is one of the most popular engineering thermoplastics and is majorly used as a replacement to metal in various applications.
The numerical label for Nylon is derived from the number of carbon atoms in the diamine and dibasic acid monomers used to manufacture it. Nylon 66 for example, is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which gives Nylon 66 or PA66 its name. The ratio of carbon atoms is what gives each nylon type its unique property characteristics.
Polyamide 12 or Nylon 12 is a high quality engineering plastic material, available in a range of grades to suit many applications.
Nylon 12 absorbs very little moisture, which means components produced using this material retain a high degree of dimensional stability. Highly processable, Nylon 12 has exceptionally strong resistance to cracking under stress, including instances when it encapsulates metal components.
Nylon 12 displays excellent resistance to chemicals, including fuels, hydraulic fluids and ketones but can be attacked by strong acids, alkalis and halogens.
