Polyisocyanurate foam and process for producing same |
| abstract |
The present invention provides for a polyisocyanurate foam comprising the reaction product of an organic polyisocyanate, a blowing agent, a catalyst and a minor amount of a polyol component, characterized in that the polyol component comprises (a) a polyester polyol having a free glycol content of less than about 7 percent by weight of the polyester polyol or (b) a mixture of the free glycol-containing polyester polyol with at least one other polyol, the total free glycol content of mixture (b) being less than about 7 percent by weight of the polyester polyol. Also disclosed is a polyurethane foam, process for production of polyisocyanurate foam and laminate products. |
