Product Description
Hydrogenated terphenyl is an excellent high-temperature heat transfer oil for liquid phase, with high thermal stability, oxidation resistance, and low vapor pressure. It is a liquid phase heat transfer oil used for heat transfer at high temperatures, and can provide reliable operation for several years even at a working temperature of 345 ℃. Our hydrogenated terphenyl passed the 350 ℃ thermal stability test of China Special Equipment Inspection and Research Institute in 2013.
L-QD350 organic heat carrier (hydrogenated terphenyl) is a high-temperature synthetic heat transfer oil, the main component of which is a mixture of partially hydrogenated terphenyl isomers. It is obtained by partial hydrogenation of a mixture of ortho-, meta-, and para-terphenyls in different proportions. Average molecular weight: 252 Appearance: Slightly yellow transparent oily liquid. Low freezing point, low permeability at high temperature, can be used in liquid phase for a long time under 350° conditions.
Main Characteristics
High Thermal Stability
The terphenyl mixture formed at high temperatures exhibits ultra-high thermal stability.
Low Coking
It is not easy to form solid particles and coke deposits, and it degrades into low molecular volatile substances, which can be self-drained through the system.
Low Vapor Pressure
The saturated vapor pressure at high temperature is low, reducing the system burden and ensuring reliable system operation.
