magnetic damping material is made from asphaltum, barium ferrite magnetic powder and other additives, the manufacture process includes mixing, calender, embossing and cutting etc. magnetic damping material can stick on the surface of iron,steel and other coating, the characteristics should include nontoxicity, odourless and nonflammable etc. Barium ferrite magnetic powder usde for auto vibration & sound damping material needs special granularity,high magnetic performance and lower price.
Unimagnet Industry Co., Ltd adopts improved technics, changed pre-sintered temperature and raw material proportion, ball mill and pelletizer technology to get high performance barium ferrite magnetic powder 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, not only in Auto vibration & sound damping material but also can be apply in train and ship vibration & noise damping material.
