Galden D02 PFPE Fluid is a specialized low‑temperature dielectric fluid manufactured by Syensqo, tailored for hermetic seal micro‑leak detection and deep‑cold reliability screening of sealed micro‑electronics. Its core advantage lies in industry‑leading‑97°C pour point, keeping free‑flowing status under extreme cold environments where other PFPE fluids turn solid.
Formulated with controlled narrow molecular weight distribution, this clear, odorless PFPE liquid retains low viscosity and low surface tension under sub‑zero temperature, enabling penetration into micro gaps of aerospace, military and automotive sealed electronic assemblies. Its inherent chemical inertness eliminates corrosion risks to metal pins, PCB substrates and various engineering plastics widely used in sealed component manufacturing.
