Phenyl silicone oil is the product of dimethyl silicone oil after part of the methyl group is replaced by phenyl. Due to the rigidity, molecular volume and polarity of phenyl group is greater than methyl group, so it has good radiation resistance and high oxidation stability, heat resistance, fire resistance, UV resistance and chemical resistance. Not only that, but also by adjusting the ratio of phenyl and methyl groups and introducing vinyl, hydrogen, hydroxyl, alkoxy, fluoroalkyl groups to the side or end groups of phenyl silicone oil, phenyl silicone oil can be more widely used. The application fields of phenyl silicone oil mainly have the following aspects:

Heat transfer oil, also known as heat carrier oil, is used for indirect heat transfer of a class of special oil with good thermal stability, heat transfer oil as an industrial oil heat transfer medium has the following characteristics: under almost normal pressure conditions, you can obtain a high operating temperature. It can greatly reduce the operating pressure and safety requirements of the high temperature heating system and improve the reliability of the system and equipment; It can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or realize the process requirements of high temperature heating and low temperature cooling with the same heat conduction oil in the same system. Can reduce the complexity of the system and operation; The water treatment system and equipment are omitted, which improves the thermal efficiency of the system, reduces the maintenance workload of equipment and pipelines, and reduces the initial investment and operating costs of the heating system.

Phenyl silicone oil not only has uniform heating, accurate temperature control, can produce high temperature under low steam pressure, good heat transfer effect, energy saving, convenient transportation and operation, thermal cracking resistance and chemical oxidation performance, good thermal stability characteristics. It can also achieve the function of high temperature heating and low temperature cooling, and greatly improve the safety performance with its 35KV/25mm super insulation, and the stabilizer with high phenyl content of phenyl silicone oil can even be used for hundreds of hours at 300 ~ 350℃.
