Abstract (en)

[origin: WO2022078899A1] Provided is a composition for forming a polyisocyanurate foam having excellent surface quality of a formed article, particularly, a polyisocyanurate foam having excellent smoothness. The invention is a composition for forming a polyisocyanurate foam, the composition comprising: a polymer having a hydroxy group; a polyisocyanate; and a foaming agent, in which the foaming agent comprises a hydrofluoroolefin; the polymer having a hydroxy group contains a polyester alcohol, and a polyether polyol having a hydroxyl value of 350 to 700 mgKOH/g and obtained by adding propylene oxide to a trifunctional polyol as a starting substance; the amount of the polyester alcohol is 15 parts by mass or more relative to 100 parts by mass of the composition; and the amount of the polyether polyol is 0.2 to 5 parts by mass relative to 100 parts by mass of the composition.
