POLYOL BLENDS CONTAINING ORTHO-CYCLOHEXANEDIAMINE-INITIATED POLYOLS FOR RIGID POLYURETHANE FOAMS. |
摘要 |
<p>Polyether polyols initiated with ortho-cyclohexanediamines such as 1,2- diaminocyclohexane are used in rigid polyurethane foam formulations in conjunction with an aromatic amine-initiated polyol, and/or with low levels of tertiary amine catalysts. The polyol mixtures are useful in making rigid polyurethane foams, especially foams for pour-in-place applications, where they give a good combination of low k-factor and short demold times.</p> |
