摘要： A method for producing a foam body (10) having an internal structure (100, 200, 300), comprising the steps: I) selecting an internal structure (100, 200, 300) to be formed in the foam body (10), the structure comprising a first polymer material; II) providing a foam body (10), the foam body (10) comprising a second polymer material which is different to the first polymer material; III) injecting, by means of an injection means (20), a predefined amount of a melt of the first polymer material or a predefined amount of a reaction mixture (30, 31, 32) which reacts to form the first polymer material at a predefined location inside the foam body (10), corresponding to a volume element of the internal structure (100, 200, 300); IV) repeating step III) for further predefined locations inside the foam body (10), corresponding to further volume elements of the internal structure (10), until the internal structure (10) is formed. The invention also relates to a foam body (10) which has an internal structure (100, 200, 300) and is obtainable by the method according to the invention.

摘要： The invention relates to flame-retardant flexible polyurethane foams with phosphazene and to methods for producing PUR flexible foams by reacting a component A containing: A1, an isocyanate-reactive component, A2, a propellant containing water, A3, optionally auxiliary agents and additives, and A4, a flame retardant, with B, an isocyanate component. The invention is characterized in that the flame retardant A4 contains a phosphazene according to the formula (I): [PmNmXk] (I), where X independently of one another represents O-aryl or NR-aryl, at least one aryl group is substituted, X can represent a bridge, R is selected from the group of H, C1-C4 alkyl, and aryl, and m represents a number from 1 to 5, particularly preferably 3 or 4, k depends on m and represents a number from 0 to 2m, and the phosphazene does not have any groups which are reactive towards isocyanates.
