Product Composition
The chemical synthetic base oil is refined by adding a certain proportion of highly efficient additives such as compounding agents and other additives at high temperatures.
Performance Characteristics
1. High heat transfer performance: it has high density, specific heat, thermal conductivity, high heat transfer efficiency, and is a heat transfer medium with excellent performance.
2. Good thermal stability: it has outstanding thermal stability and can be used for a long time with stable structure in the highest use temperature range (320℃).
3. Strong antioxidant capacity: Highly efficient antioxidants are added during the production and refining process, which improves its antioxidant capacity significantly. When exposed to air under normal temperature, the oxidation speed of this heat transfer oil slows down, which has little effect on the performance of the oil, so it can be used for a long time under normal operation.
4. low vapor pressure: it has good low vapor pressure characteristics, safe and reliable operation.
5. non-toxic, odorless, non-corrosive: non-toxic and odorless properties, especially the oil is not corrosive to the equipment, do not need to take anti-corrosion measures.
6. good mobility: low pour point, low viscosity, good pumping ability, not easy to block the pipeline and equipment, especially suitable for use in cold areas in all seasons.
