New Ferrofluids offer High Magnetization and Longer Life
BEDFORD, NH, — January 21, 2020 — Ferrotec (USA) Corporation, the US subsidiary of Ferrotec Holdings Corp., a global supplier of materials, components, and precision system solutions and the leading manufacturer of magnetic liquids, today announced the PBG-series of polyethylene glycol (PEG) based ferrofluids for bio-medical and other applications. For R&D professionals, the PBG-series ferrofluids offer high magnetization and longer life than Ferrotec’s EMG series of water-based ferrofluids and opens the door to new areas of research.
Ferrofluids are a unique class of material. A ferrofluid is a stable colloidal suspension of sub-domain magnetic nanoparticles in a liquid carrier. The particles, which have an average size of about 100Å (10 nm), are coated with a stabilizing dispersing agent (surfactant) that prevents particle agglomeration even when a strong magnetic field gradient is applied to the ferrofluid.
“With roots from the NASA space program, ferrofluid has been an inspirational driver for breakthrough technologies and applications ranging from manufacturing to electronics and even bio-medical uses. Polyethylene glycol (PEG) based ferrofluids offer high magnetization, high colloidal stability, low nonspecific binding, and biocompatibility,” said Barry Moskowitz, general manager for Ferrotec’s Electronic Devices Business Group. “For our customers that have used our EMG series of water-based ferrofluids, the PBG series will provide longer life.”
Ferrotec’s PBG series ferrofluids are available in a wide range of magnetization levels from 66 to 990 gauss with viscosity values 1 to 40 cP.
