The invention refers to an absorbent core for use in an absorbent product, suchas a sanitary napkin, a diaper, an incontinence protection or the like, the coreafter compression having a material density (based on the total content of thecore) of at least 200 kg/m3, preferably at least 230 kg/m3, measured at a pressureof 0.5 kPa whereby the absorbent core has been formed in-line as a discrete or continuouscore, characterised by that the absorbent core comprises SAP-particles, wherebyat least 99.5 % of the SAP- particles have a size of maximally 600 μm. Hereby,problems with regard to clogging of SAP-particles to compression rollers duringmanufacturing are markedly reduced. Further, the invention refers to a methodfor manufacturing the absorbent core, as well as an absorbent product comprisingthe absorbent core.
