Low amine emission polyurethane foam |
摘要 |
It is found that a polyurethane foam having significantly reduced or negligible amine emissions can be obtained by reacting a polyol with a polyisocyanate in the presence of a blowing agent being a carbamate, obtained from contacting carbon dioxide with an amine or alkanolamine, and further in the presence of a non-fugitive amine catalyst. A process is disclosed which has particular utility for the preparation of integral skinned foam, such as automotive steering wheels, exhibiting attractive physical performance and low volatile amine emissions.
