  • Process for preparing a polyisocyanurate polyurethane material
    Publication number: 20060084777
    Abstract: A process for preparing a polyisocyanurate polyurethane material comprises reacting a polyisocyanate and an isocyanate-reactive composition, wherein the reaction is conducted at an isocyanate index of 150 to 1500 and in the presence of a trimerisation catalyst, wherein the polyisocyanate consists of a) 80-100% by weight of diphenylmethane diisocyanate comprising at least 40% by weight of 4,4?-diphenylmethane diisocyanate and/or a variant of said diphenylmethane diisocyanate which variant is liquid at 25° C. and has an NCO value of at least 20% by weight, and b) 20-0% by weight of another polyisocyanate, and wherein the isocyanate-reactive composition consists of a) 80-100% by weight of a polyether polyol having an average nominal functionality of 2-6, an average equivalent weight of 150-1000, an average molecular weight of 600-5000, an oxyethylene (EO) content of 75-100% by weight, and b) 20-0% by weight of one or more other isocyanate-reactive compounds excluding water.
