flexible micro motor magnetic stripsUnimagnet has manufactured micro motor magnetic strips for six years. Based on constantly investment in research and development, our gifted team has solved many stubborn problems in the micro motor strips field, such as high temperature resistance which can reach 172 Celsius degrees, talcum powder separate problem, etc.

Unimagnet manufactures micro motor magnetic strips by mixing ferrite powder, polyethylene, plasticiser and stabilizing agent by special proportion, and adopts continuous production and multilayer roller compaction techniques. Micro motor magnetic strips has qualities of stable magnetic performance, precise shape and high temperature resistant ability.
