UOLEN10
Product Model UOLEN®10
Operating Temperature Range: -60°C to 300°C (-76°F to 572°F)
UOLEN®10 is an organosilicon-based synthetic thermal. It exhibits exceptional high-temperature stability, low viscosity at low temperatures, high flash point, high fire point, high smoke point, strong oxidation resistance, and odorless properties. This fluid is suitable for open constant-temperature systems to operate at low temperatures. As a versatile heat transfer medium, it is designed for closed-loop temperature control systems within a broad range of -60°C to 300°C (-76°F to 572°F), enabling rapid heating and cooling cycles with efficient thermal exchange performance. Additionally, UOLEN®10 demonstrates excellent dielectric strength and physiological inertness, making it ideal to use in cold plate liquid cooling systems for servers.
