Method for producing polyurethane foamed materials having an improved long-term stability |
摘要 |
Polyurethane foams having improved long-term stability are prepared by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms reactive with isocyanate groups, in the presence of inhibitors, by a process in which the inhibitors are encapsulated in a substance which is inert under the conditions of the polyurethane preparation, in particular wax.
