Product Introduction:
HDM-QE350 synthetic heat transfer oil is a synthetic heat transfer oil made of base oil synthesized from high-performance modified dibenzyl diphenyl ether and polyphenyls, and added with various high-temperature additives, which has the properties of thermal cracking and oxidation resistance. The product has good heat transfer efficiency, and its excellent viscosity characteristics make it easy to pump at startup and operating temperature. Because of their thermal cracking resistance at the recommended operating temperature, the flash points of these oils will not be significantly reduced in use. The product also shows special heating and heat conduction characteristics, and the heat dissipation is faster. Closed and open cold oil seal indirect heating and cooling systems for various industrial prcesses are recommended.
Application scope:
HDM-QE350 synthetic heat transfer oil is suitable for closed heat transfer system with heating temperature lower than 345℃ and open heat transfer system with heating temperature lower than 200℃.
Performance characteristics:
- Narrow fraction range and high initial boiling point.
- Good oxidation stability at high temperature and long service life.
- Low volatility and good fluidity at low temperature.
- High specific heat capacity. Good thermal conductivity
- Good compatibility with system materials, non-corrosive.
Technical specifications:
- GB 23971-2009
- DIN 51522-1998
