View Patent ↗Embodiments of the disclosure include aromatic polyol compositions, resin blend compositions, and spray foam compositions.
1. A spray foam composition, comprising a reaction product of an B side component comprising a resin blend composition with a A side component comprising a polyfunctional isocyanate, wherein the spray foam composition has an NCO index of about 120 to 250 at a volume ratio of A:B of about 1:1 to 3:1, wherein A is the A side component, and wherein B is the B side component, wherein the spray foam composition has a bio-based content of 7% by weight or greater as measured by ASTM 06866, wherein the resin blend composition comprises an aromatic polyol composition; a surfactant, a catalyst, and a blowing agent, wherein the aromatic polyol composition consists of the direct reaction product of: a mixture consisting essentially of di-ethyl glycol; one or more substances selected from an aromatic acid, an aromatic ester, and an aromatic anhydride; and 15 to 30% by weight of the aromatic polyol composition of tall oil fatty acid in combination with palmitic acid.
2. The spray foam composition of claim 1 , wherein the spray foam composition has an NCO index of about 220 to 250.
3. The spray foam composition of claim 1 , wherein the mixture consists essentially of di-ethyl glycol; dimethyl terephthalate; and 15 to 30% by weight of the aromatic polyol composition of tall oil fatty acid or tall oil fatty acid in combination with palmitic acid.
4. The spray foam composition of claim 3 , wherein the mixture consists essentially of di-ethyl glycol; dimethyl terephthalate; and 15 to 30% by weight of the aromatic polyol composition of tall oil fatty acid.
