This invention relates to reactive systems for the production of low density, cavity filling polyurethane foams for NVH (noise vibration and harshness) application areas in which the system exhibits reduced VOC emissions. These foams comprises an isocyanate-reactive component having a viscosity of at least about 3,000 mPa.s, at 23°C, and comprises at least one amine-initiated compound which contains isocyanate-reactive groups.
La présente invention concerne des systèmes réactifs pour la production de mousses de polyuréthane de remplissage de cavités pour des zones d'application NVH (Noise Vibration and Harshness = bruit, vibrations, et rudesse sonore, en français) dans lesquelles le système démontre des émissions de VOC (volatil organic compound, composé organique volatil, en français) réduites. Ces mousses comprennent un composant réactif isocyanate ayant une viscosité d'au moins 3 000 mPa.s environ à une température de 23° C, et comprennent au moins un composé initié amine qui contient des groupes réactifs isocyanate.
