摘要： Embodiments of the invention provide for viscoelastic polyurethane foams. The foams are made from reaction system which includes (a) an isocyanate reactive component, (b) a isocyanate component, (c) one or more blowing agents, (d) a catalyst component, and (e) a silicone based surfactant. The isocyanate reactive component includes at least (i) from 25 to 80% by weight of at least one polyoxyethylene capped polyoxypropylene/polyoxyethylene polyol having a combined number average equivalent weight from 1300 to 1700, a polyoxyethylene percentage of between 75% and 95% by weight of the combined amounts of polyoxypropylene and polyoxyethylene, and a primary OH percentage of between 80 and 95 % of the total number of OH groups of the polyoxyethylene capped polyoxypropylene/polyoxyethylene polyol, and (ii) from 5 to 30% by weight of the isocyanate reactive component of at least one low functionality polyol having a functionality of between 1.5 and 2.5, a combined number average equivalent weight from 500 to 1500 and an OH number of 40 to 70.

摘要： Polyurethane foams are made using a biuret-modified MDI and/or PMDI as the isocyanate component. The isocyanate is characterized by having a high content of biuret-containing oligomers and, preferably, a low proportion (if any) of biuret-urea oligomers. Flexible, resilient foams made using this biuret-modified isocyanate perform well on flammability tests such as the UNI 9175 CS. E. RF4 test, even without added flame retardants.

摘要： Tribromoneopentyl alcohol and 2,2-bis(chloromethyl)trimethylene bis(bis(2-chloroethyl)phosphate) are used together as flame retardants for polyurethanes. The tribromoneopentyl alcohol reacts into the polyurethane structure to introduce 2,2-bis-bromomethyl-3-bromo-1-propanyl groups which are bound to the polymer through urethane linkages. The 2,2-bis(chloromethyl)trimethylene bis(bis(2-chloroethyl)phosphate) is dissolved or dispersed in the polymer. Flexible polyurethane foams made using this combination of flame retardants often pass stringent fire tests such as the Italian UNI 9175 C.S.E. RF4 test for upholstered furniture.
