FLEXIBLE POLYURETHANE FOAM FOR HOT-PRESS MOLDING, PRODUCTION METHOD THEREFOR, HOT-PRESS MOLDED ARTICLE, AND PRODUCTION METHOD THEREFOR

摘要

Disclosed is a flexible polyurethane foam with which hot-press molding can be successfully performed that has sufficient firmness and excellent processing workability during cutting. The flexible polyurethane foam for hot-press molding is produced by reacting a polyol mixture (X) and a polyisocyanate compound in the presence of a catalyst for urethanization, a foaming agent, and a foam stabilizer. The polyol mixture (X) includes: a polyoxyalkylene polyol (A) in which the average number of hydroxyl groups is 2 to 3, the hydroxyl value is 5 to 90 mg KOH/g, and the oxyethylene group content is 0 to 30 mass%; a polyoxyalkylene polyol (B) in which the average number of hydroxyl groups is 2 to 3 and the hydroxyl value is 100 to 250 mg KOH/g; and a polyoxyalkylene mono-ol (D) in which the hydroxyl value is 5 to 200 mg KOH/g. The amount of the polyisocyanate compound used is 90 or higher on the isocyanate index.
