(57) [Summary] Lubricating oil used for a compressor or a vacuum pump, It provides a silicone organic blend with improved viscosity stability as a hydraulic oil, dielectric liquid coolant. The silicone liquid used in the silicone organic blend has a polydispersity of more than 1.5. The viscosity increase of the silicone organic blend of the present invention is less than 1 centistokes (mm 2 / s) when aged in a furnace at 100 ° C. for 14 days, whereas the polydispersity is 1.5. Commercial silicone organic blends that use smaller silicone fluids have a viscosity increase of 1.3 centistokes (mm 2 / s) or more. |
