Compacted superabsorber for use, e.g. in hygiene articles, obtained by compaction under pressure of a composition containing synthetic superabsorber particles with a high fines content

摘要

Compacted superabsorber (I), obtained by subjecting a composition containing synthetic superabsorber particles, more than 5% of which show a particle size of 250 microns or less to a specific contact pressure of at least 3 kN/cm or a pressure of at least 3 kN/cm2. Independent claims are also included for (1) a method (M1) as described above for the production of (I); (2) a method for the production of composites by bringing (I) into contact with a substrate; (3) composites obtained by this method; and (4) foam, moulded products, fibres, sheet, film, cables, sealing materials, liquid-absorbent hygiene articles, vehicles for plant growth and mould growth regulating materials, packaging materials, soil additives and building materials containing (I).
