The invention concerns parts injected with polyester based on a polyester (A) and an ethylene copolymer (B) and an unsaturated epoxide such that the weight percentage (B) x MFI (A + B) / MFI (A) is greater than 3 and in that expression: MFI(A+B) represents the modified polyester softness index, i.e. the mixture of (A) and (B) and optional fillers; MFI (A) represents the softness index of polyester (A) and optional fillers (without (B)). The weight percentage (B) represents the weight percentage of (B) in the mixture of (A) and (B) and optional fillers.
Pièces injectées en polyester à base de polyester (A) et d'un copolymère (B) de l'éthylène et d'un époxyde insaturé et telles que le pourcentage poids (B) x MFI (A + B) / MFI (A) est supérieur à 3 et dans cette expression: MFI (A + B) désigne l'indice de fluidité du polyester modifié c'est-à-dire le mélange de (A) et (B) et des charges éventuelles. MFI (A) désigne l'indice de fluidité du polyester (A) et de charges éventuelles (sans (B)). Le pourcentage poids (B) désigne le pourcentage poids de (B) dans le mélange de (A) et (B) et des charges éventuelles.
