ASA vs PC+ABS : différences clés
The ASA (Luran) 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.
The ASA supporte des températures plus élevées (HDT 103 °C contre 88 °C pour le PC+ABS), ce qui le rend plus adapté aux environnements chauds.
The PC+ABS présente une résistance à la traction supérieure (48.4 MPa contre 40.8 MPa pour le ASA).
the chemical resistance du ASA est supérieure à celle du PC+ABS (70/100 contre 40/100).
The PC+ABS s'injecte plus facilement (difficulté 2/5 contre 4/5 pour le ASA).
The PC+ABS offre un meilleur rapport coût/performance à la transformation (75/100 contre 60/100 pour le ASA).
