This invention disclosure relates to a process to make flexible open cell polyurethane foam with optimum mechanical properties and lowest chemical emissions. Using the selection of tertiary amine catalysts together with a group of carboxylic acids according to this disclosure can produce foam products with optimum properties and lowest chemical emanations.

Reducing emissions in polyurethane foam

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 ageing.

Silicone surfactants for the production of open cell polyurethane flexible foams

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.
