Galden HS240 – 240℃ High Temperature VPS PFPE Fluid
Material: PFPE (Perfluoropolyether)
Density (25℃): 1.82 g/cm³
Boiling Point: 240℃
Viscosity (25℃): 5.30 cSt
Packing: 5 KG / drum
Galden HS240 is a medium-high boiling point perfluoropolyether (PFPE) fluid specifically designed for Vapor Phase Soldering (VPS) of lead-free and high-temperature solder alloys. Manufactured by Syensqo (formerly Solvay), this fluid features a narrow molecular weight distribution, combined with the very strong carbon-fluorine bond and flexible ether link, providing the properties that make Galden HS240 ideal for VPS applications requiring a 240℃ process temperature.
With a boiling point of 240℃, Galden HS240 bridges the gap between the LS230 (230℃) and HS260 (260℃), offering a versatile solution for electronics manufacturers who need higher process temperatures than LS230 but do not require the extreme 260℃ of HS260. Its balanced viscosity (5.30 cSt at 25℃) ensures efficient heat transfer and excellent wetting of solder joints across a broad range of applications.
