Pour Point: -100℃
Viscosity (25℃): 1.00 cSt
Packing: 5 KG / drum
Galden HT135A is an aerospace-grade perfluoropolyether (PFPE) heat transfer fluid within the Galden HT series. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid has a boiling point of 135 °C, a pour point of -100 °C, and a kinematic viscosity of 1.00 cSt at 25 °C. It is officially listed as AIRBUS APPROVED (AIRBUS HOMOLOGADO), making it a trusted choice for demanding aerospace and defense thermal management applications.
Galden HT135A is engineered for avionics cooling, test baths, high-voltage environments, and automated test equipment (ATE) systems. Its PFPE chemical体系 provides excellent chemical inertness, high dielectric strength (40 kV at 2.54mm gap), and outstanding thermal stability. The fluid is non-flammable, non-toxic, evaporates without residue, and offers broad compatibility with metals, elastomers, and plastics.
