1. A fiber-containing product comprising:
a cured binder is formed from a binder composition comprising:
a sugar alcohol; and
a polymeric polycarboxylic acid,
wherein the binder composition is characterized by a mole ratio of hydroxyl groups to carboxylic acid groups greater than or about 1.1:1, and
wherein the fiber-containing product is characterized by a thermal stability that is greater than a comparative fiber-containing product made with a comparative cured binder that includes the polymeric polycarboxylic acid but lacks the sugar alcohol wherein the fiber-containing product exhibits a combustion exotherm at a higher temperature than a comparative fiber-containing product made with a comparative cured binder that includes said polymeric polycarboxylic acid but lacks said sugar alcohol, and wherein the cured binder contains less than or equal to 1 wt. % unpolymerized sugar alcohol.
