Polyamide (Nylon 12) is significantly more expensive than Polyamide 6 (PA6) and even Polyamide 66 (PA 66), so is not so in demand as PA 6 and PA 66. Polyamide 12 is recommended where components are operating in a wet environment, exposed to high loads (eg shipbuilding).
In the absence of moisture or high loads (mechanical, electrical, thermal) is possible to choose from a wide range of other more economical engineering plastics.
Polyamide 12 (PA 12) - Polyamide 12 – is a semi-crystalline polyamide with very high toughness and good chemical resistance. Of all the polyamides, Polyamide 12 is characterized by the lowest water absorption. It also has good impact resistance. Some of the properties of Polyamide 12 are:
- Lowest water absorption
- Very good impact resistance and notched impact resistance
- Good chemical resistance
- Very good stress cracking resistance
- Good sliding properties
