Abstract: A flexible polyurethane foam comprises the reaction product of an isocyanate component and an isocyanate-reactive component in the presence of a blowing agent. The isocyanate component comprises a polymeric diphenylmethane diisocyanate component and a monomeric diphenylmethane diisocyanate component. The monomeric diphenylmethane diisocyanate component comprises 2,4'- diphenylmethane diisocyanate and 4,4' -diphenylmethane diisocyanate. The isocyanate-reactive component comprises a polyether polyol having a molecular weight of from about 700 to about 20,000 and a plurality of terminal caps which are substantially free of ethylene oxide groups. The flexible polyurethane foam is substantially free of supplemental flame retardant additives and exhibits flame retardance under flammability tests according to California Technical Bulletin 117 regulations.

Abstract: A single layer flexible foam includes the reaction product of an (A) isocyanate component and a (B) isocyanate -reactive component. The isocyanate component and the isocyanate-reactive component react in the presence of a (C) polyurethane gel. The polyurethane gel has a viscosity of from about 3,000 to about 12,000 cps at 25°C and includes the reaction product of a polyol component and a second isocyanate component which react at an isocyanate index of from about 10 to about 70. The flexible foam also includes a plurality of agglomerated gel substrates that are formed from the polyurethane gel and that are dispersed in the flexible foam. The flexible foam is formed using a method including the steps of providing (A), providing (B), providing (C), and combining (C) with (A) and (B), such that (A) and (B) react in the presence of (C) to form the flexible foam.

Abstract: The subject disclosure provides a viscoelastic polyurethane foam and a method of forming the viscoelastic polyurethane foam. The viscoelastic polyurethane foam comprises the reaction product of a toluene diisocyanate and an isocyanate reactive component. The isocyanate reactive component comprises a first polyether triol, a second polyether triol, an amino alcohol chain extender, and a hydrolyzable polyether polydimethylsiloxane copolymer. The first polyether triol has a weight-average molecular weight of from 500 to 5,000 g/mol, at least 60 parts by weight ethyleneoxy units, based on the total weight of the first polyether triol, and at least 10% ethyleneoxy end caps. The second polyether triol, which is different from the first polyether triol, has a weight-average molecular weight of from 5,000 to 10,000 g/mol and at least 80% ethyleneoxy end caps.
