Polyisocyanurate foam articles |
| abstract |
Novel integral-skinned polyisocyanurate foams are described, which are characterized by their improved impact resistance. The foams are prepared by conventional integral-skin foam forming techniques. The improved structural properties are obtained by employing as a polyol component of the foam forming mixture, a mixture of (a) from about 5 percent to about 60 percent by weight of a polyol having a functionality of from 2 to 8 and an equivalent weight of from 30 to 200, with (b) from about 40 percent to about 95 percent by weight of a polyether polyol having a functionality of from 2 to 3 and an equivalent weight of from about 750 to about 2100; provided that when said polyether polyol is a triol having an equivalent weight of from about 1500 to about 2100, at least about 50 percent of the hydroxyl groups thereof are primary hydroxyls. The improved foams of the invention are particularly useful as structural materials, where high impact resistance is required. |
