Technical properties
Built for a wide liquid range and stable process performance
Ideal for heat transfer applications with a wide liquid range from -50 degrees C to 270 degrees C, non-conductive behaviour and strong chemical stability.
PFPE heat transfer fluids offer a strong combination of thermal resilience, dielectric performance and long service life. They are suited to processes where conventional fluids struggle with oxidation, ignition risk or aggressive chemistries.
