Product description
Hydrogenated terbiphenyls are good liquid-phase high-temperature thermal conductive oils with high thermal stability, oxidation resistance and low vapor pressure.It is a liquid-phase thermal oil used for heat transfer at high temperatures. It can provide reliable operation for several years even at a operating temperature of 345℃.Our company's hydrogenated terbiphenyls passed the thermal stability test of 350℃ by the China Institute of Special Equipment Testing and Research in 2013.
L-QD350 organic heat carrier (hydrogenated triphthalene) is a high-temperature synthetic heat conduction oil, the main component is a mixture of partially hydrogenated triphthalene isomers.It is obtained by partial hydrogenation of a mixture of o-, m-, and p-terephthalates in different proportions.Average molecular weight: 252 Appearance: yellowish transparent oily liquid.The freezing point is low, the permeability is small at high temperatures, and the liquid phase can be used for a long time under 350° conditions.
Main features
High thermal stability
The mixture of terbiphenyls formed at high temperature has ultra-high thermal stability.
Low coking properties
It is not easy to form solid particles and coke scale, and it degrades into low molecular weight volatiles, which can be discharged by the system.
Low vapor pressure
The saturated vapor pressure at high temperature is low, which reduces the burden on the system and ensures reliable system operation.
