Title:
フォームを改善するための低官能価天然油系化合物の使用
Document Type and Number:
Japanese Patent JP2010538149
Kind Code:
A
Abstract:
Isocyanate reactive materials of natural origin having an average isocyanate reactive functionality of less than about 1.5 can be used to enhance polyurethane foams. For instance, use of such materials often results in more open foams than is obtained in the same formulation without the materials. The materials also help maximize the level of renewable resource materials used in foams, especially with viscoelastic foams. The invention includes a polyol composition comprising at least one natural oil isocyanate reactive material having an average isocyanate reactive functionality of less than 1.5 in an amount greater than that naturally present in any natural oil polyol in the composition. While it is preferred to include at least one natural oil polyol in the polyol composition, doing so is optional. The invention additionally includes a process of preparing a polyurethane comprising (a) supplying an isocyanate composition comprising at least one polyisocyanate; (b) supplying at least one polyol composition as previously described; (c) admixing the isocyanate composition and the polyol composition; and (d) exposing the admixture to reaction conditions such that at least one polyurethane is formed.
