Unimagnet provides bonded magnetic ferrite powder, which can mix with rubber, CPE-135, Stabilizer etc. It can produce various flexible magnets, eg: magnetic sheets, magnetic strips and other complex shape flexible magnet by calendering, injection or extruding process. Bonded ferrite powder includes barium ferrite material and strontium ferrite material.
Unimagnet is engaged in constant research and development, which provides superior barium magnetic ferrite powder in Auto vibration & noise damping material and fridge magnetic material.
