Abstract
(EN)
Provided is a polymer composition comprising a thermoplastic, an ethylene alpha-olefm plastomer, a fibrous inosilicate and a slip agent. The polymer composition exhibits superior scratch and mar resistance as indicated by a Ford Five Finger scratch resistance on Ford Fawn 2ZK grain of at least 15 N. Also provided are shaped articles made from the polymer compositions. Also provided are methods for making scratch and mar resistant polymer compositions. Finally, articles made from the polymer compositions are also provided, particularly automotive exterior, interior and fascia parts, requiring scratch and mar resistance.

La présente invention concerne une composition à base de polymères comportant une matière thermoplastique, un plastomère alpha-oléfine d'éthylène, un inosilicate fibreux et un agent glissant. La composition à base de polymères présente une résistance supérieure aux rayures et aux éraflures telle qu'indiquée par une résistance aux rayures de type Ford Five Finger sur grain Ford Fawn 2ZK d'au moins 15N. L'invention concerne également des articles façonnés réalisés à partir des compositions à base de polymères. L'invention concerne en outre des procédés de fabrication de compositions à base de polymères résistantes aux rayures et aux éraflures. L'invention concerne enfin des articles réalisés à partir des compositions à base de polymères, notamment des pièces de véhicule automobile extérieures, intérieures et de carénage frontal, nécessitant une résistance aux rayures et aux éraflures.
