Process for the preparation of flexible polyurethane foams |
| abstract |
A process for the preparation of flexible polyurethane foams comprising the steps of : (a) bringing together a polyol component, a polyisocyanate component, a blowing agent comprising liquid carbon dioxide, a suitable catalyst and optionally ancillary chemicals at sufficient pressure to maintain the carbon dioxide in a liquid state, and (b) releasing the pressure and allowing the mixture obtained in step (a) to react into a flexible polyurethane foam. The polyol component comprises a polymer polyol consisting of at least one polyether polyol having an average nominal functionality of at least 2.5 with dispersed therein from 2 to 50 wt% of polymer particles based on total weight of polymer polyol. The particle size of none of the polymer particles exceeds 50 micron. |
