| 20080262168 | Process For Preparing a Polyisocyanurate Polyurethane Material - A process for preparing a polyisocyanurate polyurethane material, which process comprises reacting a polyisocyanate and an isocyanate-reactive composition, wherein the reaction is conducted at an isocyanate index of 1600 to 100,000 and in the presence of a trimerisation catalyst, wherein the polyisocyanate comprises a) 75-100% by weight of diphenylmethane di-isocyanate comprising at least 40%, preferably at least 60% and most preferably at least 85% 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 (polyisocyanate a), and b) 25-0% by weight of another polyisocyanate (polyisocyanate b), the amount of polyisocyanate a) and polyisocyanate b) being calculated on the total amount of this polyisocyanate a) and polyisocyanate b), and wherein the isocyanate-reactive composition comprises a) 80-100% by weight of a polyether polyol having an average nominal functionality of 2-6, an average equivalent weight of 1100-5000 and an oxyethylene (EO) content of 65-100% by weight and b) 20-0% by weight of one or more other isocyanate-reactive compounds, the amount of polyol a) and isocyanate-reactive compound b) being calculated on the total amount of this polyol a) and compound b). | 10-23-2008 |
| 20090005517 | Process for Making a Polyisocyanurate Composite - Process for making a polyisocyanurate composite which process comprises combining a polyisocyanate, a polyether polyol and a trimerization catalyst with a to-be-bonded material to form a reactive composite, and allowing in a next step this reactive composite to react at elevated temperature, wherein the amount of the reactive binder composition is 1-60% by weight and the amount of the to-be-bonded material is 40-99% by weight, both calculated on the amount of the reactive binder composition plus the amount of the to-be-bonded material, wherein the amount of the polyisocyanate and the polyol is such that the index is 150-10000, characterized in that the polyol is a polyol having an average equivalent weight of 100-2500 and an oxyethylene content of at least 50% by weight. | 01-01-2009 |
