Composition for injection molding and method for producing same

Provided is a composition for injection molding comprising a ferrite powder formed from aggregates of ferrite particles; a first binder; and a second binder. The second binder has a lower softening point than the first binder; the ferrite powder has a weight (Wp) and a specific surface area (S); the...

More Information
Summary:Provided is a composition for injection molding comprising a ferrite powder formed from aggregates of ferrite particles; a first binder; and a second binder. The second binder has a lower softening point than the first binder; the ferrite powder has a weight (Wp) and a specific surface area (S); the first and second binders have a weight (Wb1 and Wb2) and a density (Db1 and Db2); and the virtual thickness (Tb1) of the first binder is between 0.6 and 3.0, while the virtual thickness (Tb2) of the second binder is between 5.0 and 16.0. Preferably, coated ferrite particles wherein the outside circumference of the ferrite particles is coated by the first and second binders are present in the composition. Formula 1: Tb1[nm] = (Wb1 * 103)/(Db1 * Wp * S), formula 2: Tb2 [nm] = (Wb2 * 103)/(Db2 * Wp * S).
