Abstract

L'invention concerne la stabilisation d'une mousse de polyuréthanne à résilience élevée. Pour stabiliser la mousse de polyuréthanne, on incorpore au polyol de départ une certaine proportion d'une substance particulaire solide finement divisée présentant, à l'état dispersé, des dimensions maximales efficaces de particules inférieures environ 75 mu . Application de ces mousses : matériau d'amortissement ou de rembourrage.The invention relates to the stabilization of a high resilience polyurethane foam. To stabilize the polyurethane foam, a proportion of a finely divided solid particulate material having, in the dispersed state, maximum effective particle sizes of about 75 µm is incorporated into the starting polyol. Application of these foams: cushioning or padding material.
