    Abstract: Embodiments of the present disclosure are foam formulations. As an example, foam formulation can include a polyol composition having an amine-imitated polyol that is from 10 percent to 20 percent of a total weight of the polyol composition and an additional polyol that is from 80 percent to 90 percent of the total weight of the polyol composition, a polyisocyanate, a blowing catalyst, and a gel catalyst, where a combination of the blowing catalyst and the gel catalyst is from 0.5 percent to 1.5 percent the total weight of the polyol composition and where the blowing catalyst is from 50 percent to 100 percent of a total weight of the blowing catalyst and the gel catalyst.

    Abstract: A formulation for preparing a low density, full water blown polyurethane rigid foam includes an isocyanate component; an isocyanate-reactive component comprising from 30-50 wt % of a first polyether polyol having a functionality greater than 5 and an OH value from 350-550 mgKOH/g; from 5 to 25 wt % of a diol having an OH value from 100-300 mgKOH/g; and from 15 to 35 weight percent of a second polyether polyol having a functionality from 3 to 5; further including from 1.5 to 5 wt % of a catalyst selected from dimethylbenzylamine and/or 1,2-dimethyl-imidazole; from greater than 0 to 1 wt % of a trimerization catalyst selected from a glycine salt and/or tris(dimethyl aminomethyl) phenol; greater than 4.1 wt % water as a blowing agent; and any additional constituents selected such that the formulation, excluding the isocyanate component, totals 100 wt % and, the formulation absent the isocyanate component, has a dynamic viscosity from 540 to 864 mPa*s at 20° C. Processing under one-shot conditions can yield a rigid form having a molecular weight per crosslink ratio from 380 to 420. The formulation offers good processability, while the foam shows desirable dimensional stability and mechanical properties at unexpectedly low applied density.

    Abstract: Embodiments of the present disclosure provide for a composition for forming a polyurethane foam and a method of forming the polyurethane foam using the composition. The polyurethane foam includes a formulated polyol, an isocyanate and a blowing agent. The formulated polyol includes 60 weight percent (wt. %) to 80 wt. % of a polyether polyol and 10 wt. % to 25 wt. % of an aromatic polyester polyol, where the wt. % are based on a total weight of the formulated polyol, and where the formulated polyol has a polyol mixture functionality of 3.8 to 5.5.
