PURPOSE:To prepare the title fluid which exhibits a high electroviscous effect due to the polarizing effect of a conductive carbon in fine particles, can be used at a temp. as high as 150 deg.C or higher because the fluid scarcely contains water, and is so stable that no oxidation nor degradation occurs. CONSTITUTION:The title fluid comprises an electrical insulating oil and fine particles covered with a fluorinated pitch and dispersed in the oil. |
