Excellent product performance
1. Thermal stability: (the most important performance)
This product selects base oils and additives with excellent thermal stability, so the product has excellent thermal stability. Reduce carbon deposits, reduce volatility, maintain good heat transfer performance and temperature control accuracy.
2. Oxidation stability: (one of the important performance)
This product selects base oils with excellent antioxidant properties and high-temperature antioxidant and anti-fouling additives, which can inhibit the speed of oxidized sludge generation and the tendency of deposition and scaling, so that the system maintains a good heat transfer effect.
3. Low volatility: (energy saving and long life)
The initial distillation point is used to indicate the volatility of the heat transfer fluid. The higher initial distillation point of this product gives it a very low vapor pressure and volatilization loss, which can ensure the stability of system operation.
4. Better safety
The flash point and auto-ignition point are used to indicate the safety of the heat transfer fluid. This product has a higher flash point and auto-ignition point, which can ensure the safety of system operation.
5. Heat transfer performance
This product has suitable viscosity, high specific heat and thermal conductivity, can effectively transfer or absorb heat, and improve fuel economy and operating efficiency.
