PA66 (Extruded Polyamide 66)

Polyamide 66, better known as PA66, is an extruded polyamide, which is usually required for small dimensioned application and when PA6 properties are no more enough.


Compared to PA6, PA66 offers higher rigidity, hardness, thermal dimension stability, wear resistance, impact and low frictional properties. On the other hand, PA66 tends to absorb an higher quantity of moisture and water, so it is suitable to substitute it with PA6G, available in bigger sizes and with most economical prices.

Chemical resistance.

About its chemical resistance, PA66 is comparable to PA6.

Miscellaneous information.

Our Polyamide 66 is FDA approved and can also be certified according EC 1935/2004, EC 2023/2006 and EU 10/2011.

According the incredible improvement of plastic science, Polyamide 66 has been improved a lot in last few years, thanks to a different type of additives, such as:

  • Molybdenum Disulphide. Improved sliding properties at slightly higher compressive strength; UV radiation resistant by its black colour; improved wear resistance and lower surface friction.
  • Glass Fibre. Improved mechanical resistance; higher abrasion.
  • Polyethylene. Improved wear resistance and friction.

PA66 most famous brand name.

Extruded Polyamide 6, usually available in rods, tubes and plates, is produced by different Companies, each one with its own commercial name. Although that, each PA66 has more less the same characteristics and can easily substitute one each other.

Most famous brand names are:

  • Nylon 66;
  • Zellamid® 250;
  • Ertalon® 66 SA;
  • Lamigamid® 200;
  • Tecamid® 66;
  • Sustamid® 66.
