Methyl phenyl silicone oil has higher viscosity temperature coefficient, lower freezing point and flash point than dimethyl silicone oil with the same viscosity, and its compression resistance changes faster under pressure. Low phenyl silicone oil has remarkable low temperature resistance and fluidity at - 70 ℃. With the increase of phenyl mole fraction, the high temperature resistance, irradiation resistance, lubricity and solubility in organic solvents of silicone oil were improved; But the low temperature resistance decreased. Silicone oil with high phenyl mole fraction
When heated above 250 ℃, oxidation occurs and the viscosity increases; In particular, silicone oil with 50% phenyl mole fraction can be used for hundreds of hours at 300 ~ 350 ℃ with the addition of stabilizer
