High Flash Point Heat Transfer Oil 300°C Thermal Fluid Sinopec Great Wall L-QB300

Sinopec Great Wall L-QB300 High Flash Point Heat Transfer Oil 300°C Thermal Fluid

Sinopec Great Wall L-QB300 High Flash Point Heat Transfer Oil

Sinopec Great Wall L-QB300 is a mineral oil type heat transfer oil engineered for demanding high-temperature heat transfer duties. It is blended from refined narrow-cut mineral base oils together with detergent-dispersant and anti-oxidation additives, which give the oil a high flash point and strong thermal stability for continuous service in open and closed systems with a maximum bulk oil temperature of 300°C.

Heat transfer oil has to move heat steadily for years without breaking down, and that is exactly what this thermal fluid is designed to do. Its high flash point reduces fire risk where hot fluid meets air, while low volatility limits oil consumption and keeps circuits clean at elevated temperatures. Good oxidation and thermal stability resist coking and sludge deposition, so the thermal fluid holds its heat transfer performance and the system keeps its temperature control steady. With good low-temperature fluidity, the oil also starts easily in cold climates, and its metal compatibility protects pipes, pumps and seals from corrosion.

L-QB300 heat transfer oil is widely specified where process reliability matters. In petrochemical plants, synthetic fiber lines, resin reactors, pharmaceutical heating skids and dyeing equipment, the fluid must carry heat evenly day after day without coking or thickening. By combining a high flash point, low volatility and dependable oxidation stability, this thermal fluid helps operators hold tight temperature control, cut topping-up frequency and extend fluid change intervals.

Product Q&A

Q: Why does a high flash point matter for a heat transfer oil?
A: A high flash point lowers the risk of fire and explosion, especially in open systems where the hot fluid surface meets air. It is one of the first safety parameters engineers check when they select a thermal fluid.

Q: Can L-QB300 serve systems running at 300°C?
A: Yes. This heat transfer oil is formulated for a maximum bulk oil temperature up to 300°C, and its thermal stability keeps heat transfer performance steady during sustained high-temperature operation.

Q: How does low volatility help my system?
A: Low volatility means less oil evaporates at high temperature, so oil consumption falls, the circuit stays clean and the film on hot surfaces is maintained for reliable heat transfer.

Q: Which industries use this thermal fluid?
A: It is widely used in petrochemical, synthetic fiber, synthetic resin, pharmaceutical, printing and dyeing processes, wherever stable high-temperature heating is required.
