The polyol-containing composition for obtaining a polyurethane foam by reacting with a polyisocyanate, the polyol-containing composition comprising a polyol, a catalyst, a foaming agent, and a filler, a content of the filler in the polyol-containing composition being 8 mass % or more, the catalyst comprising a metal catalyst containing at least one selected from the group consisting of bismuth and tin.

Abstract: The present invention relates to a polyol composition for obtaining a polyurethane foam through a reaction with a polyisocyanate compound. The polyol composition comprises a polyol, a catalyst, a foam stabilizer, a foaming agent, and ammonium carboxylate, wherein the ammonium carboxylate has a quaternary ammonium cation as a cationic moiety, and a carboxylic acid anion represented by formula (1) as an anionic moiety.

Abstract: A polyurethane composition raw material liquid agent filled in a cartridge-like container comprises a polyol or a polyisocyanate, and a filler, wherein the polyurethane composition raw material liquid agent has a viscosity at 25° C. and a rotation speed of 10 rpm of 2300 mPa·s or more. The filler may include a solid flame retardant. The polyurethane composition raw material liquid agent and another polyurethane composition raw material liquid agent are mixed and discharged to form a polyurethane composition.

Abstract: A flame-retardant rigid polyurethane foam contains a flame retardant, the foam having a ratio of the maximum peak intensity ratio (P1) of the foam after moist heat treatment of the foam for one week at a temperature of 80° C. and a humidity of 85% to the maximum peak intensity ratio (P2) of the foam before this moist heat treatment of 85% or more (P1/P2x100). The P1 and P2 each refer to the ratio of the maximum peak intensity of 1390 to 1430 cm?1 to the maximum peak intensity of 1500 to 1520 cm?1 when the infrared absorption spectrum is measured at a position 5 to 10 mm from the surface of the foam, and the average intensity of 1900 to 2000 cm?1 is adjusted to zero.
