| titleOfInvention | Flexible foam |
| abstract | The invention relates to a composition for preparing a flexible foam and its application. The composition comprises the following components: a. an isocyanate mixture; b. a polymer polyol mixture; c. an isocyanate-reactive group-containing compound having a number average molecular weight of 32-400 g/mol; d. an aqueous alkali metal salt solution, having a concentration of greater than or equal to 1.5% and less than 30%, and a pH value of less than 9.5; and e. a metal catalyst; wherein the amount of the tertiary amine catalyst in the composition is not more than 0.1wt%, and the isocyanate index of the composition is 70-120. The composition has a high reaction efficiency and can meet the quantitative production requirements of the textile industry. The flexible foam prepared from the composition has a good phenolic yellowing resistance, and can meet the comprehensive requirements of the textile industry for a high rebound resilience, a good gas permeability, a ultraviolet yellowing resistance and the like of the foam. |
