Galden HT80 80 °C Low Viscosity PFPE Heat Transfer Fluid
Material: PFPE (Perfluoropolyether)
Boiling Point: 80℃
Pour Point: -110℃
Viscosity (25℃): 0.570 cSt
Packing: 5 KG / drum
Galden HT80 is an ultra-low-viscosity perfluoropolyether (PFPE) heat transfer fluid within the Galden HT series. It delivers the second-lowest viscosity in the HT series at 0.570 cSt and a pour point of -110 °C. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid has a boiling point of 80 °C. It offers an excellent balance of flow performance and low-temperature capability for medium-temperature thermal management tasks.
Galden HT80 provides exceptional flow characteristics when compared with higher‑viscosity HT90 (1.50 cSt) and HT110 (0.770 cSt). Its -110 °C pour point is the second-lowest in the HT series, after HT55, enabling reliable pumpability even under extreme cold conditions. This makes Galden HT80 an ideal choice for systems that require near-ultra-low viscosity and dependable cold‑start operation at medium temperatures up to 80 °C.
