Title:
高粘度指数の、幅広い温度で機能性を有する流体組成物、その製造方法およびその用途
Document Type and Number:
Japanese Patent JP2006509899
Kind Code:
A
Abstract:
This invention relates to lubricants comprising base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at -30 C or lower and the methods of making them. Specifically, the present invention relates to novel high viscosity index, low-viscosity lubricants usable as wide-temperature lubricants, for example hyrdraulic oils, comprising novel low-viscosity base stocks, with improved performance in low-temperature viscosity, and methods to produce them.
