Pellets - POLYMAG
EMC/EMI absorption pellets merge NANOMAG magnetic powders (MnZn, Fe₃O₄...) with tailored polymer matrices. The powders supply electromagnetic properties, in order to optimize permeability, permittivity, reflectivity and also reflection loss, while the polymers provide the mechanical performance the application demands, like flexibility, rigidity, heat resistance...
These pellets also enable the synthesis of filaments FILAMAG-T & FILAMAG-F.
