Abstract (en)

[origin: EP0310346A2] The present invention discloses a composition suitable for use in traction drives, which comprises a small amount of an antioxidant in combination with a naphthenic oil having as a main component thereof a condensed polycyclic alicyclic hydrocarbon resulting from the hydrogenation of a hydrocarbon oil obtained by decomposing a coat type raw material oil. The sum of the carbon atoms of the condensed polycyclic alicyclic hydrocarbon and the carbon atoms directly bonded to the polycyclic moiety accounts for not less than 80% of the total number of carbon atoms of the naphthenic oil and the hydrogen/carbon atomic ratio (H/C) of the naphthenic oil is in the range of 1.68 to 1.80.
