Polyamide 12 - Nylon 12 - PA 12

Polymer Type

Thermoplastic

Advantages

Lowest water absorption approximately 2% at saturation hence good dimensional stability and electrical properties. Tougher than Nylon 11 and Very flexible grades available.

Disadvantages

Expensive. Lowest strength and heat resistance of any Polyamide unmodified generic.

Applications

Precision engineering components, components requiring low temperature toughness. Sports shoe soles.
