EMG Series - Oil-based Ferrofluid
Type: EMG 909
Ferrotec’s EMG 909 Ferrofluid is a member of Ferrotec’s family of EMG Series - Oil-based ferrofluids. Unlike Ferrotec’s APG series of ferrofluids that have been optimized for audio speaker applications, Ferrotec’s EMG Series ferrofluids address a broad range of application requirements and can be used for experimentation and application development. Ferrotec’s oil-based EMG Series are typically used in applications where you don’t want evaporation or you don’t want the ferrofluid to mix the other elements. EMG 909 ferrofluid is Black-brown fluid.
