| Abstract | The present invention provides a composition for flame retardant flexible polyurethane foam comprising: (i) a polyol component; (ii) a polyisocyanate component; (iii) a halogen free phosphate ester that meets the following conditions (a) to (d), and that contains at least one alcoholic hydroxyl group: (a) an acid value of 2 KOHmg/g or less, (b) a viscosity of 5 Pa's or less at 25 C., (c) a hydroxyl value of 5 to 250 KOHmg/g, and (d) a weight average molecular weight of 200 to 2000; (iv) a tertiary amine carboxylate; (v) a Silicone foam Stabilizer; and (vi) a blowing agent. The composition for flame-retardant flexible polyurethane foam of the present invention can give a flexible polyurethane foam that has Satisfactory flame retardant properties, as well as excellent properties Such as better heat resistance, fogging resistance and Scorch resistance and extremely low com pression Strain. |
