Hydrogenated terphenyl is an excellent high-temperature heat transfer fluid for liquid phase applications, possessing high thermal stability, oxidation resistance, and low vapor pressure. It is used as a liquid phase heat transfer fluid at high temperatures and can provide reliable operation for several years even at an operating temperature of 345 ℃. Our company's hydrogenated terphenyl passed the 350 ℃ thermal stability test of the China Special Equipment Inspection and Research Institute in 2013.

Diisopropylbiphenyl (DIPB) is a high-purity, single synthetic aromatic hydrocarbon compound. It possesses the high thermal stability, excellent fluidity, and heat transfer performance required for high-temperature applications (Max. 350°C) of synthetic heat transfer oils.

Biphenyl diphenyl ether mixture heat transfer oil is a gas/liquid dual-purpose high-temperature synthetic organic heat carrier with high thermal stability, consisting of a eutectic mixture of 26.5% biphenyl and 73.5% diphenyl ether.

Methyl hexahydrophthalic anhydride is refined from the catalytic hydrofining of methyl tetrahydrophthalic anhydride, methyl hexahydrophthalic anhydride, MHHPA.
