    Abstract: Hydrophilic open-celled resilient foams containing melamine-formaldehyde resins, characterized by a droplet absorption rate of less than 5 seconds and an EU standard EN ISO 14184-1 formaldehyde emission of less than 100 mg of formaldehyde/kg of foam, and obtainable by(a) heating an aqueous solution or dispersion each containing at least a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a curing agent to form a foam and crosslink the precondensate,(b) then conditioning the foam at from 120 to 300° C. for from 1 to 180 minutes to remove volatiles, and(c) treating the foam during the conditioning or thereafter with at least one hydrophilicizer and/or with ozone, a corona discharge or a plasma,are useful in hygiene articles to acquire, distribute and immobilize body fluids.

    Abstract: The invention relates to hydrophilic, open-cell, elastic foams consisting of melamine/formaldehyde resins. Said foams can be obtained by (a) heating and cross-linking an aqueous solution or dispersion, containing, respectively, at least one melamine/formaldehyde precondensate, an emulsifier, an expanding agent and a hardener, a foam being formed, (b) subsequently tempering the foam for a period of 1 to 180 minutes at 120 to 300 DEG C, volatile parts being removed, and (c) treating the foam with at least one polymer during or after the tempering process, said polymer containing primary and/or secondary amino groups and having a molar mass of at least 300. The invention also relates to a method for producing the hydrophilic, open-cell, elastic foams and to their use in hygiene products for absorbing, distributing and immobilising bodily fluids.
