Moretec Group is manufacturer and worldwide supplier of vacuum feedthrough (Magnetic fluid seals)for PVD, CVD, FPD, Sputtering System, Ion Implantation, Czochralski (CZ) Growing Equipment and Vacuum Robot etc. R&D and engineering team are in Japan and production in China.
Magnetic fluid / ferrofluid consists of sub-micron particles of Fe3O4 (other paramagnetic metallic oxides), surfactant and carrier liquid, etc. The surface of the particle is coated with surfactant, so that the magnetic particle is able to be dispersed stably in the liquid. Thus, it becomes a liquid of stable suspensibility. Because the liquid contains super-paramagnetic particles, it acts magnetically as a whole though it is a liquid.
