Title:
FERRITE-RESIN COMPOSITE COMPOSITION
Document Type and Number:
Japanese Patent JPH04154869
Kind Code:
A
Abstract:
PURPOSE:To obtain a ferrite-resin composite composition having large magnetic permeability and excellent flow property, suitable for electromagnetic wave- absorbing material and electromagnetic wave-shielding material by blending manganese-zinc ferrite globular particulate powder having large magnetic permeability and proper dimensions with a resin composition. CONSTITUTION:Globular manganese-zinc ferrite powder consisting of 47-58mol% Fe2O3, 22-30mol% MnO and 15-30mol% ZnO, having 20-150mum average particle diameter, which is formed of crystalline particles having 5-15mum average diameter, is blended with a resin composition to provide the objective ferrite-resin composite composition having >=25 magnetic permeability.
