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