Galden HS235 – 235℃ High Stability VPS PFPE Fluid
Material: PFPE (Perfluoropolyether)
Boiling Point: 235℃
Density (25℃): 1.79 g/cm³
Vapor Pressure (25℃): < 1 mmHg
Packing: 5 KG / drum
Galden HS235 is a high-stability perfluoropolyether (PFPE) fluid within the Galden LS/HS series, specifically engineered for demanding Vapor Phase Soldering (VPS) applications. Produced by Syensqo, formerly Solvay, this fluid has a boiling point of 235 °C and a density of 1.79 g/cm³ at 25 °C. The HS grade offers enhanced thermal stability, minimizing fluid degradation during extended production runs.
Galden HS235 is designed for high-melting-point lead-free solder alloys and high-reliability applications in aerospace, medical, and automotive sectors. Its very strong carbon-fluorine bond and flexible ether link provide exceptional chemical and thermal stability, with a decomposition temperature above 290 °C. The fluid is RoHS compliant, non-corrosive, non-flammable, non-toxic, and evaporates without residue.
