Claims17
A thermal or acoustical fiberglass insulation material comprising:
- (a) a collection of glass fibers;
- and
- (b) a binder disposed on the collection of glass fibers, wherein the binder comprises i) at least one reaction product of a reducing sugar reactant and an amine reactant, wherein the percent by dry weight of the reducing sugar reactant with respect to the total weight of reactants ranges from about 73% to about 96%, ii) a silicon-containing coupling agent, and iii) optionally, a corrosion inhibitor, wherein the fiberglass material comprises less than 99% by weight and more than 75% by weight glass fibers, and wherein the fiberglass material has a density of from about 0.4 lbs/ft3 to about 6 lbs/ft3.
A thermal or acoustical fiberglass insulation material comprising:
- (a) a collection of glass fibers;
- and
- (b) a binder disposed on the collection of glass fibers, the binder comprising i) a mixture of Maillard reactants, wherein the percent by dry weight of a reducing sugar reactant with respect to the total weight of reactants ranges from about 73% to about 96%, ii) a silicon-containing coupling agent, and iii) optionally, a corrosion inhibitor, wherein the fiberglass material comprises less than 99% by weight and more than 75% by weight glass fibers, and wherein the fiberglass material has a density in the range from about 0.4 lbs/ft3 to about 6 lbs/ft3.
A thermal or acoustical fiberglass insulation material comprising:
- (a) a collection of glass fibers;
- and
- (b) a binder disposed on the collection of glass fibers, wherein the binder comprises i) at least one reaction product of a reducing sugar reactant and a polycarboxylic acid ammonium salt reactant, wherein the percent by dry weight of the reducing sugar reactant with respect to the total weight of reactants ranges from about 73% to about 96%, ii) a silicon-containing coupling agent, and iii) optionally, a corrosion inhibitor, wherein the fiberglass material comprises less than 99% by weight and more than 75% by weight glass fibers, and wherein the fiberglass material has a density in the range from about 0.4 lbs/ft3 to about 6 lbs/ft3.
