Thermosetting binder composition for manufacturing insulation products containing a water-soluble oligomer ester

Abstract

A thermosetting binder composition containing water and a water-soluble oligomer ester of at least one carbohydrate selected from reducing sugars, non-reducing sugars and hydrogenated sugars, hydrogenated sugars being selected from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol and the hydrogenation products of starch hydrolysates or of hydrolysates of lignocellulosic materials; at least one diol; and at least one polycarboxylic acid, the binder composition having a solid matter content ranging between 40% and 80% by weight, the water-soluble oligomer ester accounting for at least 70% by weight of the solid matter of the thermosetting binder composition, and the ratio of the number of hydroxyl groups of all the diols to the number of hydroxyl groups of all the diols and carbohydrates ranging between 5% and 50%.
