PA6 vs PA12 : différences clés

The PA6 (Ultramid, Durethan, Badamid,Technyl) et le Polyamide 12 are two plastic materials frequently put in competition when selecting material for injection-moulded parts. This technical comparison helps you identify the most suitable material for your specifications.

The PA6 supporte des températures plus élevées (HDT 65 °C contre 55 °C pour le PA12), ce qui le rend plus adapté aux environnements chauds.

On the pull PA6 est plus résistant (75 MPa contre 50 MPa pour le PA12).

the chemical resistance du PA6 est supérieure à celle du PA12 (85/100 contre 70/100).

Les deux matières présentent une difficulté d'injection comparable (2/5).

The PA6 is generally cheaper à transformer que le PA12 (score coût 85/100 contre 55/100).

Our recommendation

In summary, the PA6 est supérieur au PA12 sur les trois critères principaux : haute température, contraintes mécaniques et coût de revient. Le PA12 peut néanmoins être préférable selon des contraintes spécifiques (disponibilité, compatibilité chimique, transparence...). Nos ingénieurs matières Hybster can accompany you.
