Abstract: 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.

Abstract: The invention relates to methods for producing melamine/formaldehyde foams, comprising the method steps of: a) producing an aqueous mixture M1) that comprises 100 parts by weight of at least one melamine/formaldehyde pre-condensate, 2 to 4 parts by weight of at least one hardener, 0.2 to 5 parts by weight of a surfactant mixture, 0.1 to 5 parts by weight of at least one salt of an inorganic acid or a salt of an organic carboxylic acid, 1 to 40 parts by weight of at least one blowing agent, 0 to 5 parts by weight of at least one colouring agent and/or optical brightener, 0 to 20 parts by weight of one or more further additives, and 25 to 60 parts by weight of water, b) heating and foaming the mixture M1) using microwave radiation, c) crosslinking and hardening the foam that has been formed, with the aid of the hardener and microwave radiation, d) drying said foam using microwave radiation, and e) tempering the dried foam using hot air. According to the invention, it is essential for the mixture M1) to contain, as a surfactant mixture, a mixture consisting of 50 to 90 wt.% of an anionic surfactant and 10 to 50 wt.% of a non-ionic surfactant, these weight percentages each relating to the total weight of the surfactant mixture. The invention also relates to melamine/formaldehyde foams that can be produced according to the method in the invention, as well as to the uses of same.
