Abstract

Procédé de fabrication d'une mousse de polyuréthane flexible, dans lequel on fait réagir un isocyanate avec un polyol en présence d'un agent formateur de mousse et d'un additif retardateur de combustion, tel que la mélamine, tandis que le polyol, est un polyol modifié par un polymère. Utilisation en tant que matières structurales élastiques, et notamment pour le rembourrage ou l'amortissement des articles d'ameublement.
