For Loudspeakers, Seals, Experiments and Educators

Ferrofluids are a unique class of material. A ferrofluid is a stable colloidal suspension of sub-domain magnetic nano particles in a liquid carrier. The particles, which have an average size of about 100Ă… (10 nm), are coated with a stabilizing dispersing agent (surfactant) which prevents particle agglomeration even when a strong magnetic field gradient is applied to the ferrofluid.

Ferrotec ferrofluids are uniquely optimized to maximize performance in specific applications. Within each product series, you’ll find that each product family offers a number of different ferrofluids with a variety of material properties and performance characteristics.
