Galden HT170 170 °C Low Viscosity PFPE Heat Transfer Fluid
Material: PFPE (Perfluoropolyether)
Boiling Point: 170℃
Pour Point: -97℃
Viscosity (25℃): 1.80 cSt
Packing: 5 KG / drum
Galden HT170 is a low-viscosity perfluoropolyether (PFPE) heat transfer fluid within the Galden HT series. It delivers the lowest viscosity at 1.80 cSt among all HT grades with boiling points above 170 °C. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid has a boiling point of 170 °C. It offers a great balance of low-temperature fluidity and high-temperature stability for demanding thermal management tasks.
Galden HT170 shows far superior flow performance when compared with higher‑viscosity HT200 (2.40 cSt) and HT230 (4.40 cSt). Its pour point of -97 °C is one of the lowest in the HT series, ensuring excellent pumpability even under cold conditions. This makes Galden HT170 an ideal choice for systems that require efficient heat transfer at high temperatures while maintaining outstanding flow characteristics.
