REDUCTION OF VOC EMISSIONS FROM LOW DENSITY CAVITY FILLING NVH POLYURETHANE FOAMS

摘要

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.
