Title
(EN) VISCOELASTIC POLYURETHANE FOAMS WITH REDUCED TEMPERATURE SENSITIVITY
(FR) MOUSSES DE POLYURÉTHANE VISCOÉLASTIQUES À SENSIBILITÉ À LA TEMPÉRATURE RÉDUITE
Abstract
(EN)
This invention relates to a process for preparing viscoelastic polyurethane foam in which the isocyanate-reactive component comprises a specific polyol blend, and to viscoelastic polyurethane foam wherein the isocyanate-reactive comprises the specific polyol blend. The polyol blend may be an in situ formed polyol blend.
(FR)
La présente invention concerne un procédé de préparation de mousse de polyuréthane viscoélastique dans laquelle le composant réactif à l'isocyanate comprend un mélange de polyols spécifiques, et une mousse de polyuréthane viscoélastique, cette dernière comprenant le mélange de polyols spécifiques. Le mélange de polyols peut être un mélange de polyols formé in situ.
