Beschreibung
Zusammenfassung:	Shaped flexible hot-cure PU foam article, preferably mattress and/or cushion, wherein the flexible PU foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one blowing agent and one or more catalysts that catalyze the isocyanate-polyol and/or isocyanate-water reactions and/or isocyanate trimerization, foam stabilizer and further additives, characterized in that the foam stabilizer comprises at least one compound of formula (1) [R1 2R2SiO1/2]a [R1 3SiO1/2]b [R1 2SiO2/2]c [R1R2SiO2/2]d [R3SiO3/2]e [SiO4/2]f Gg. Article façonné en mousse PU souple à durcissement à température élevée, préférentiellement un matelas et/ou un coussin, la mousse PU souple ayant été obtenue par réaction d'au moins un composant polyol et d'au moins un composant isocyanate en présence d'au moins un agent gonflant et d'un ou de plusieurs catalyseurs qui catalysent les réactions isocyanate-polyol et/ou isocyanate-eau et/ou la trimérisation d'isocyanate, et d'un stabilisateur de mousse et d'autres additifs, caractérisé en ce que le stabilisateur de mousse comprend au moins un composé de formule (1) [R1 2R2SiO1/2]a [R1 3SiO1/2]b [R1 2SiO2/2]c [R1R2SiO2/2]d [R3SiO3/2]e [SiO4/2]f Gg.
