  • Patent number: 9266994
    Abstract: An expandable polyurethane composition contains (A) a polyisocyanate, (B) an active hydrogen containing compound containing (B1) a polyol and (B2) water, and (C) a cross-linking agent composition. The cross-linking agent composition (C) contains a cross-linking agent (C1) and a carboxylic acid (C2). The cross-linking agent (C1) can be selected from an alkanolamine (a) represented by an expression: HxR1yN((R2O)nH)3-x-y, and an aminosilane (b) represented by an expression: (R3O)qR43-qSi—R5—(NHCH2CH2)pNR6R7. A content of the cross-linking agent composition (C) is 0.1 parts by mass to 20 parts by mass relative to 100 parts by mass of the active hydrogen containing compound (B), and the containing number of moles of the cross-linking agent (C1) is larger than that of the carboxylic acid (C2).

  • Publication number: 20150038604
    Abstract: An expandable polyurethane composition includes (A) polyisocyanate, (B) active hydrogen containing compound including (B1) polyol and (B2) water, catalysts, and (C) cross-linking agent composition. The (C) cross-linking agent composition includes at least one kind of (C1) cross-linking agent selected from (CA) ethoxylate derivative having MW of 2000 or less and (CB) ester compound having MW of 2500 or less, and (C2) non-protic polar solvent, and a mass ratio ((a+b)/c) of a sum of content a of the (CA) ethoxylate derivative and content b of the (CB) ester compound relative to content c of the (C2) non-protic polar solvent is 1/10 to 10/1. A flexible polyurethane foam can be obtained of which wet set is improved and feeling is good.
