Galden HT270 – 270℃ High Boiling PFPE Heat Transfer Fluid

Galden HT270 is a high-boiling perfluoropolyether (PFPE) heat transfer fluid specifically engineered for demanding high-temperature thermal management applications. Manufactured by Syensqo (formerly Solvay), this inert, dielectric, and non-flammable fluid features a boiling point of 270°C, enabling reliable heat transfer performance at elevated temperatures where other fluids would degrade or evaporate. Its high molecular weight (1550 amu) and excellent thermal stability make it the preferred choice for the most demanding high-temperature applications.

Galden HT270 offers outstanding dielectric properties, including a volume resistance of 6×10¹⁵ ohms·cm and a dielectric strength of 40 kV, providing safe operation in direct contact with energized electronic components. With a low vapor pressure of less than 10⁻² torr, it minimizes evaporation losses even at elevated temperatures, ensuring long-term system stability and reduced maintenance requirements. Its chemical inertness and non-flammability make it suitable for hazardous environments.
