Title (EN) TOUGH POLYAMIDE MOULDING MATERIAL
(FR) MATÉRIAU À MOULER DE POLYAMIDE TENACE
Abstract:
(EN) The present invention relates to a moulding material which consists to an extent of at least 50 wt%of the combination of the following constituents: a) 80 to 95 parts by mass of a polyamide component comprising a1) 70 to 100 parts by wt of PA PACMX and a2) 30 to 0 parts by wt of a linear aliphatic polyamide, b) 19 to 4 parts by mass of a core-shell impact modifier, and c) 5 to 1 parts by mass of a functionalised styrene-ethylene/butylene-styrene block copolymer as an impact modifier, wherein the parts by mass of a), b) and c) sum to 100. The moulding material of the present invention has a high transparency and a very good notched impact strength.
(FR) La présente invention concerne un matériau à mouler qui consiste en une quantité d'au moins 50 % en poids de la combinaison des constituants suivants : a) 80 à 95 parties en poids d'un constituant polyamide comprenant a1) 70 à 100 parties en poids de PA PACMX et a2) 30 à 0 parties en poids d'un polyamide aliphatique linéaire ; b) 19 à 4 parties en poids d'un modifiant choc cœur-coque et c) 5 à 1 parties en masse d'un copolymère à blocs styrène-éthylène/butylène-styrène fonctionnalisés en tant que modifiant choc, la somme des parties en poids de a), de b) et de c) étant de 100. Le matériau à mouler de la présente invention présente une grande transparence et une très bonne résistance au choc sur barreau entaillé.
