    摘要: A process for generating a non-spherical shaped particles comprising the steps of: extruding a material through an extruder nozzle orifice along an extruding axis, and. slicing the extruded material into extruded elements having a predetermined length (L). Wherein the temperature at the nozzle is kept at a temperature Tn, where Tn=Tm−T, and T is greater than about 20 C, Tm being the melting temperature of said material. Where said extruder nozzle orifice has a predetermined cross-sectional shape on a plane perpendicular to said extruding axis, said predetermined cross-sectional shape being the inverse image of the predetermined cross-sectional shape of the extruded elements, wherein said non-spherical shaped particles comprise elements having a longitudinal length (L) where the ratio of said length (L) to a perimeter-equivalent diameter of said predetermined cross-sectional shape “ECD PHull” is between about 0.5 and about 5.
