| Résumé : |
Additives often consist of additive mixtures of heterogeneous components. Their anisometry leads to part properties that depend very strongly on the orientation of the additives. For this reason, it is essential to ‧describe such orientation behavior at an early phase of development when additized plastics parts are being designed. |
