Performance Advantages
Wide Temperature Adaptability
It maintains stable physical and chemical properties from low temperature of -30°C up to high working temperature of 310°C. Moderate viscosity at low temperature ensures smooth system startup; excellent thermal stability at high temperature resists thermal decomposition.
Excellent Heat Transfer Efficiency
Extremely low kinematic viscosity of 1 mm²/s @ 40°C brings low flow resistance and high heat exchange efficiency. Combined with low density of 0.85 g/cm³, it provides superior volumetric heat capacity and reduces system energy consumption.
High Safety Performance
Flash point over 172°C, fire point up to 330°C, autoignition point above 360°C. Compared with flammable solvents, it greatly reduces fire risks and improves industrial production safety.
Long Service Life
With excellent thermal decomposition resistance under normal working conditions, its service life reaches 2–3 times that of traditional mineral thermal oil, lowering maintenance frequency and fluid replacement cost.
Good Material Compatibility
Non-corrosive to ferrous metals, non-ferrous metals and most sealing materials, compatible with most industrial heat exchange systems.
Application Fields
Typical Application Scenarios
