Flexible Magnetic Extrusions (Flexible Magnetic Strips) and Custom Profile are thermoplastic permanent magnetic Extrusions. It can provide superior holding power and widely used in stationery, household appliance, water-tight appliance. According to its magnetic property, it is divided into anisotropic and isotropic; According to its magnetization way, it is divided into surface magnetization and penetration magnetization (longitudinal, transverse and bilateral).
