Abstract

L'invention a pour objet une composition de résine de polyacétal présentant une aptitude au glissement et une résistance à l'abrasion excellentes, et permettant de réaliser des pièces moulées exemptes de problèmes comme l'abrasion et les bruits tels que les grincements provoqués par l'abrasion, même lorsque ces pièces sont utilisées dans des conditions de charge importante et de vitesse de glissement élevée, même lorsque les pièces de glissement correspondantes sont réalisées dans n'importe quel type de plastique ou de métal. La résine contient 0,5 à 15 parties en poids d'élastomère oléfinique, 0,1 à 5 parties en poids d'ester d'acide gras comportant au moins 12 atomes de carbone et, si nécessaire, 0,05 à 5 parties en poids de poudre micronisée de polytétrafluoroéthylène pour 100 parties en poids de résine de polyacétal.
