Introduction of BSG Materials’ Products

Magnetorheological Fluid(MRF)

MRF is a special fluid whose viscosity (flow resistance) changes instantly when subjected to an external magnetic field. Due to this characteristic, MRF can effectively control external shocks or vibrations in real time. Its applications are diverse, including vehicle suspension, vibration control of building structures, and shock absorption of industrial machinery.

Usage Instructions

The anti-settling design ensures that there is no performance degradation even when not used for a long time, but separation between magnetic particles and carrier fluid may occur slightly, so it is recommended to homogenize it through stirring or shaking before use. Since it is designed with excellent redispersibility of magnetic particles, it can be easily homogenized with small energy.

Storage

When not in use, ensure that the container is tightly sealed for storage.
