Abstract: The present invention relates to a thermosetting binder composition containing water and a water-soluble oligomeric ester of at least one saccharide chosen from reducing sugars, non-reducing sugars and hydrogenated sugars, the hydrogenated sugars being chosen from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol and hydrogenation products of hydrolyzates of starch or of lignocellulose materials, and of at least one polycarboxylic acid, the binder composition having a dry matter content of between 50% and 80% by weight, the water-soluble oligomeric ester representing at least 80% by weight, preferably at least 90% by weight, of the cry matter content of the thermosetting binder composition, and the thermosetting binder composition containing less than 10% by weight, preferably less than 5% by weight, with respect to its dry matter content, of free sorbitol.
It also relates to the use of such a binder composition for the manufacture of a product based on mineral or organic fibers which are bonded by an insoluble organic binder.

Abstract: A process for the manufacture of an insulating product based on mineral fibres bonded by an organic binder, includes applying a sizing composition to the mineral fibres, forming an assembly of the mineral fibres, heating the assembly of mineral fibres until the sizing composition has cured, wherein the sizing composition includes the following constituents within the limits defined below, expressed as fractions by weight with respect to the total weight of the composition: from 80% to 98% of water, from 2% to 20% of water-soluble poly(furfuryl alcohol) and less than 0.5% of furfuryl alcohol, and the mineral fibres are fibres of aluminosilicate glass including aluminum oxide, Al2O3, in a fraction by weight of between 14% and 28%.

Abstract: An aqueous poly(furfuryl alcohol) solution contains: from 40% to 85% by weight of poly(furfuryl alcohol), from 15% to 60% by weight of water, and less than 1.5% by weight of furfuryl alcohol. The solution exhibits a pH of greater than 7.0, preferably of between 7.2 and 10.0. A process for the manufacture of a product based on mineral or organic fibers which are bonded by an organic binder can use such an aqueous poly(furfuryl alcohol) solution in the diluted form.

Abstract: An insulating product includes mineral fibers of aluminosilicate glass including aluminum oxide, Al2O3, in a fraction by weight of between 14% and 28%, that are sized with a sizing composition including the following constituents within the limits defined below, expressed as fractions by weight with respect to the total weight of the composition: from 80% to 98% of water, from 2% to 20% of water-soluble poly(furfuryl alcohol), which is obtained by polycondensation of furfuryl alcohol, and less than 0.5% of furfuryl alcohol, wherein a sum of the fractions by weight of the poly (furfuryl alcohol) and of the water is at least 95%, and wherein the sizing composition applied to the mineral fibres has a pH in a range from 5 to 8.

Abstract: A process for the manufacture of a solid thermoset foam includes the following successive stages: (a) making available an expandable and thermosetting composition containing a sugar and an acid catalyst chosen from strong acids, phosphoric acid and acidic inorganic salts, (b) introducing the expandable and thermosetting composition into a mold or applying the expandable composition to a support as a film with a thickness at least equal to 1 mm, and (c) heating the expandable and thermosetting composition to a temperature at least equal to 140° C., so as to form a block of solid thermoset foam.
