ORGANOMINERAL FOAMED MATERIALS AND PROCESS FOR THEIR PREPARATION |
| 摘要 |
The foams are produced by reacting polyisocyanate and waterglass without use of a blowing agent. Foaming of the reaction mixture is achieved by the CO2, released in the reaction of isocyanate groups with water, in a controlled manner by the addition of a polysiloxane/polyether block copolymer. |
