Abstract
Official abstract text for this publication.
The general inventive concepts relate to unbonded loosefill fiberglass compositions useful for insulation. The compositions demonstrate improved product density. In certain instances, this is accomplished by application of a surface modifying agent.
First claim
Opening claim text (preview).
What is claimed is: 1 . A pourable or blowable loosefill insulation product consisting essentially of: a) glass fiber insulation wool, said glass fiber insulation wool comprising a plurality of short, chopped glass fibers of the same glass composition; b) a modifying agent applied to the surface of the glass fibers in an amount of 0.1% or less by weight; and wherein the modifying agent is the reaction product of tetraethylenepentamine and a C 6 -C 20 fatty acid. 2 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is present in an amount of 0.02% to 0.1% by weight of the pourable or blowable loosefill insulation. 3 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is the reaction product of tetraethylenepentamine and stearic acid. 4 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is as follows: 5 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is present in an amount of 0.02% to 0.08% by weight of the pourable or blowable loosefill insulation. 6 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is present in an amount of 0.02% to 0.06% by weight of the pourable or blowable loosefill insulation. 7 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is present in an amount of 0.03% to 0.06% by weight of the pourable or blowable loosefill insulation. 8 . The pourable or blowable loosefill insulation product of claim 1 , wherein the modifying agent is present in an amount of 0.04% to 0.06% by weight of the pourable or blowable loosefill insulation.
