Where can I find the physical properties of heat transfer oil?
It can be requested from the users or the design institute.
The viscosity of the synthetic heat transfer oil is 19–23； 1. Durable ； 2. High price. The viscosity of mineral oil should be over 30 degrees ； 1. Low price ； 2. The service life is 3-5 years; it is difficult to clean, and it generates a lot of impurities after use. The thermal conductivity of phenyl ether-based heat transfer oils is around 3–7 degrees ； 1. It is also used to synthesize heat transfer oil, and it has good low-temperature performance ； 2. High price, low flash point, has an explosive limit, and produces an unpleasant odor when used. It is recommended to avoid making such choices as much as possible.
After further processing, Jiuxing synthetic heat transfer oil contains few impurities; its annual loss is 5%, its oxidation resistance lasts up to 400 minutes, its annual coking rate is only one in ten thousand, and its thermal expansion rate at high temperatures is one in a thousand. Its oxidation resistance and thermal stability are superior to those of alkane-based heat transfer oils, and under standard conditions its service life ranges from 5 to 10 years. Technical Parameters
