EMG Series - Water-based Ferrofluid
Type: EMG 509
China Advanced Ceramic EMG 509 Ferrofluid is a member of China Advanced Ceramic family of EMG Series - Water-based ferrofluids. Unlike China Advanced Ceramic APG series of ferrofluids that have been optimized for audio speaker applications, China Advanced Ceramic EMG Series ferrofluids address a broad range of application requirements and can be used for experimentation and application development. China Advanced Ceramic water-based EMG Series are typically used in applications where rapid evaporation or the ability to mix ferrofluid into a water-based system is required. EMG 509 ferrofluid is Black-brown fluid and uses Anionic surfactant.
