摘要： The invention relates to foams comprising microballoons for sound absorption, comprising 40 to 85 wt % of open-cell polymer foam and 15 to 60 wt % of microballoons having a flexible outer coating, wherein the microballoons have a D50 value of at least 70 μm and no greater than 250 μm, relative to the total weight of polymer foam and microballoons, and to a method for the production thereof, comprising the steps I) impregnating an open-cell polymer foam with a liquid dispersion comprising expandable microballoons, II) optionally pressing/compressing and/or drying the polymer foam, and III) heat treating the impregnated polymer foam at a temperature above the expansion temperature and below the decomposition temperature of the expandable microballoons, for expanding the microballoons.

摘要： The invention relates to a foam material that is produced from a hydrophobic or oloephobic, open-pored foam matrix. Said matrix is impregnated with a substance consisting essentially of a polyvinylidene halide (co)polymer, which can optionally contain additional substituents and also optionally of a fluorocarbon resin and/or a silicone resin. The invention also relates to a method for producing said foam material.

摘要： The invention relates to processes for producing melamine-formaldehyde foams comprising the consecutive steps a) and b): a) heating a mixture comprising a melamine-formaldehyde precondensate, a curative and a blowing agent to foam up and crosslink said mixture, and b) tempering the foam obtained in step a), wherein it is essential to the present invention that - step a) utilizes a precondensate which has a melamine:formaldehyde molar ratio in the range from 1:2.1 to 1:3.9, and - which has a sulfite group content, based on the total weight of the melamine-formaldehyde precondensate, in the range from 0% to 1% by weight, and - said tempering in step b) is effected at a temperature in the range from 230 to 290°C, and also to melamine-formaldehyde foams obtainable according to the processes of the invention, and to uses thereof.

摘要： The invention relates to a method for the production of an abrasive foam on the basis of a melamine-formaldehyde-condensation product comprising inorganic nanoparticles, with the following steps: (1) Producing a solution or dispersion comprising a precondensate of the foam to be produced and inorganic nanoparticles, (2) foaming the precondensate by heating the solution or dispersion from step (1), in order to obtain a foam comprising inorganic nanoparticles, and if applicable (3) tempering the foam obtained in step (2), which leads to an increased abrasion when polishing delicate surfaces.
