More Information
Summary:Provided for are lubricant base stocks with improved filterability. The lubricant base stock includes a bright stock or a heavy neutral and an effective amount of a pour point depressant. The filterability of the base stock as measured by the Membrane Filtration Method is less than or equal to 400 seconds. Also provided for are lubricating oils with improved filterability and methods of improving the filterability of lubricant base stocks. La présente invention concerne des huiles de base lubrifiantes ayant une filtrabilité améliorée. L'huile de base lubrifiante comprend une base lubrifiante de haute viscosité et une quantité efficace d'un abaisseur de point d'écoulement. La filtrabilité de l'huile de base telle que mesurée par la méthode de filtration sur membrane est inférieure ou égale à 400 secondes. La présente invention concerne en outre des huiles lubrifiantes ayant une filtrabilité améliorée et des procédés d'amélioration de la filtrabilité d'huiles de base lubrifiantes.
