Features:
The product has passed the GB23971-2009 national type test, its thermal stability and thermal conductivity are good, and the specific heat value is high. For example, the thermal conductivity curve, density curve and viscosity curve have significant advantages over ordinary heat transfer oil. The chemical properties of the heat transfer oil are relatively stable. It is not as easy to burn as the light oil. The maximum temperature can reach 300 °C. It is a high-tech achievement transformation project in Shanghai. It is comparable to the heat transfer oils of Mobil 603, British BP and Shell.
1. Better thermal stability, less coking and longer service life;
2. Good thermal conductivity, flow performance and pumpability;
3, low toxicity and tasteless, does not corrode equipment, has little impact on the environment.
