20070225393, Sep 27, 2007

Filed:

Mar 27, 2006

Appl. No.:

11/389771

Inventors:

Allen Arnold - Catasauqua PA, US
James Tobias - Center Valley PA, US
Andrea Bell - Pottstown PA, US

International Classification:

C08G 18/16
C08G 18/00

US Classification:

521161000, 528048000

Abstract:

A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and amidoamine and/or imidazoline crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show excellent resistance to deterioration of physical properties upon humid ageing.

US Classification:

521125

Abstract:

A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and an alkylated polyamine crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show improved resistance to deterioration of physical properties upon humid aging.

Abstract:

A method for preparing a flexible or semi-flexible polyurethane foam by reacting an organic polyisocyanate with a polyol in the presence of urethane catalyst, water as a blowing agent, optionally a silicone surfactant, and a cell opening additive characterized in that the cell opening additive comprises an aqueous dispersion of particles comprising a wax substance and optionally an emulsifier, at least 35% of the particles having a size of 0. 2 to 5 microns and a melting point which ranges from 0 to 55. degree. C. below the maximum foam exotherm temperature.
