ABS vs PC+ABS : différences clés
The ABS (Grade générique) et le PC+ABS 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.
Les deux matières présentent une tenue en température similaire (HDT ≈ 88 °C).
The PC+ABS présente une résistance à la traction supérieure (48.4 MPa contre 45 MPa pour le ABS).
Les deux matières présentent une difficulté d'injection comparable (2/5).

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