| titleOfInvention | PROCEDURE FOR MANUFACTURING A FLEXIBLE POLYURETHANE FOAM. |
| abstract | Process for preparing a flexible polyurethane foam comprising reacting at an isocyanate index of 70 to 130, 1) 40-65 parts by weight of a polyisocyanate composition (polyisocyanate 1) comprising: a) 80-100% in weight of a diphenylmethane diisocyanate (MDI) component comprising, based on 100 parts by weight of the MDI component, 1) 75-100 parts by weight of diphenylmethane diisocyanate comprising 15-75 parts by weight of 4, 4 diphenylmethane diisocyanate, and from 25 to 85 parts by weight of 2,4,4-MDI, and 2,2-MDI, and / or a liquid variant of such diphenylmethane diisocyanate, and 2) from 0 to 25 parts in weight of diphenylmethane diisocyanate homologs having an isocyanate functionality of 3 or more; and b) 20-0% by weight of toluene diisocyanate; 2) from 20 to 45 parts by weight of a polyether polyol (polyol 2) having an average molecular weight of 4500-10000, an average nominal functionality of 2-6 and comprising oxypropylene groups and optionally oxyethylene, the number of groups being oxypropylene of at least 70% by weight calculated with respect to the weight of this polyol; 3) 3 to 20 parts by weight of a polyether polyol (polyol 3) having an average molecular weight of 700-4000, an average nominal functionality of 2-6 and a hydroxyl number of at most 225 mg KOH / g and which it comprises oxyethylene groups and optionally oxypropylene, the amount of oxyethylene groups being at least 70% by weight calculated with respect to the weight of this polyol; and 4) 2-6 parts by weight of water, the amount of polyisocyanate 1), polyol 2), polyol 3) and water being 100 parts by weight. |
