Abstract

Embodiments of the present disclosure are directed towards formulated polyol compositions that include a sucrose propoxylated polyol, a polyether triol, and a propoxylated homopolymer triol.

First claim

What is claimed:

1. A formulated polyol composition comprising:
a sucrose propoxylated polyol having an average hydroxyl functionality from 3.0 to 6.0, an average hydroxyl number from 360 to 460 mg KOH/g, and a number average molecular weight from 400 to 800;
a polyether triol having an average hydroxyl functionality from 2.6 to 3.4, an average hydroxyl number from 100 to 200 mg KOH/g, and a number average molecular weight from 900 to 1200;
a propoxylated homopolymer triol having an average hydroxyl functionality from 2.6 to 3.4, an average hydroxyl number from 300 to 500 mg KOH/g, and a number average molecular weight from 250 to 650,
wherein the sucrose propoxylated polyol is from 21 to 31 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition, wherein the polyether triol is from 12 to 22 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition, and wherein the propoxylated homopolymer triol is from 0.1 to 8.0 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition;

a surfactant;
water;
a crosslinker; and
a catalyst selected from a blowing catalyst, a gel catalyst, and combinations thereof.

2. The formulated polyol composition of claim 1 , wherein the formulated polyol composition includes a flame retardant.

3. The formulated polyol composition of claim 1 , wherein the surfactant is from is from 0.5 to 5.0 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition.

4. The formulated polyol composition of claim 1 , wherein the water is from 11 to 21 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition.

5. The formulated polyol composition of claim 1 , wherein the crosslinker is from 0.5 to 5 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition.

6. The formulated polyol composition of claim 1 , wherein the catalyst is from 2 to 7 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition.

7. The formulated polyol composition of claim 2 , wherein the flame retardant is from 15 to 35 parts of the formulated polyol composition based upon 100 parts of the formulated polyol composition.

8. A foam formulation comprising:
the formulated polyol composition of claim 1 ; and
an isocyanate, wherein the isocyanate is from 90 to 130 parts of the foam formulation based upon 100 parts of the formulated polyol composition.

9. A foam product formed by curing the foam formulation of claim 8 .
