Magnetic damping material is made from asphaltum, barium ferrite magnetic powder and other additives,and the manufacture process includes mixing, calendering, embossing and cutting, etc. Magnetic damping material can stick on the surface of iron,steel and other coating,and the it has the characteristics of nontoxicity, odourlessness and nonflammability etc. Barium ferrite magnetic powder is used for auto vibration & noise damping material which needs special granularity,high magnetic performance and lower price.
Unimagnet adopts improved technics, changed pre-sintered temperature and raw material proportion, ball mill and pelletizer technology to get barium ferrite magnetic powder of high performance and low cost.Barium ferrite magnetic powder of this grade has competitive price. Further more, the improved technics has expanded new application field of barium ferrite magnetic powder, which is not only applied in Auto vibration & noise damping material but also in train and ship vibration & noise damping material.
