A fibrous insulation product is discloses comprising a plurality of randomly oriented fibers and a thermoset aqueous binder composition at least partially coating said fibers. The binder composition comprises at least one long-chain polyol having at least two hydroxyl groups and a number average molecular weight of at least 2,000 Daltons, a cross-linking agent comprising at least two carboxylic acid groups, and a short-chain polyol having at least two hydroxyl groups and a number average molecular weight less than 2,000 Daltons, wherein a ratio of long-chain polyol to short-chain polyol is from 0.1/0.9 to 0.9/0.1.

Insulation products formed with aqueous binder compositions

A fibrous insulation product comprising a plurality of randomly oriented glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the fibers is disclosed. The cross-linked formaldehyde-free binder composition is formed from an aqueous binder composition comprising 5.0% by weight to 37.0% by weight of at least one monomeric polyol having at least four hydroxyl groups and at least 50.0% by weight of a cross-linking agent comprising a polymeric polycarboxylic acid having at least two carboxylic acid groups, based on the total solids content of the aqueous binder composition. The glass fibers have an average fiber diameter in the range of 8 HT to 12 HT. The fibrous insulation product, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf.

Fiberglass insulation product

An aqueous binder composition is disclosed that comprises at least one long-chain polyol having at least two hydroxyl groups and a number average molecular weight of at least 2,000 Daltons; a primary cross-linking agent comprising at least two carboxylic acid groups; and a secondary cross-linking agent comprising a short-chain polyol having at least two hydroxyl groups and a number average molecular weight less than 2,000 Daltons.
