| titleOfInvention | Polyol composition and polyurethane foam |
| abstract | An object of the present invention is to provide a polyol composition capable of suppressing the occurrence of scorch even in the case of a large scale or in the case of decreasing the density of foam by increasing the amount of use of a foaming agent in the production of polyurethane foam. And a method of producing a polyurethane foam using the same. A polyol composition containing a polyol (A) and an antioxidant (B) having a solubility parameter (SP value) of 8.9 to 10.5, which is a total of formaldehyde and acetaldehyde in the polyol composition. Antioxidant (B1) having a content of 4.0 ppm or less and having, as the antioxidant (B), an SP value having an absolute value of a difference from the SP value of (A) of 0.05 or more and less than 0.60 And an antioxidant (B2) having an SP value having an absolute value of a difference from the SP value of (A) of 0.60 or more and 1.70 or less, and the total content of the antioxidant (B) in the polyol composition Polyol composition whose quantity is 500-10000 ppm. 【Selection chart】 None |
