*1 wt/% loss Temp. (TGA): The temperature at which 1% of the weight is reduced by evaporation or vaporization during heating. (Measurement conditions: Heat up 10°C per minute with a TGA measuring instrument)
*Actual operating temperature varies depending on conditions such as temperature applied to the ferrofluid, RPM, shaft diameter, and operating time.
Please determine the operating temperature considering the above conditions.
*Besides the above products, we can make custom orders

*We do not use PFAS (per- and polyfluoroalkyl substances) in our ferrofluid.
