SOFT POLYURETHANE FOAM AND SEAT PAD

The present invention provides a soft polyurethane foam obtained by foam molding a foaming stock solution containing a polyol, a polyisocyanate, a foaming agent, and a catalyst. The polyol includes a polyether polyol A having a weight average molecular weight (Mw) of 3,000 to 8,000 and 3 to 4 functi...

Zusammenfassung:	The present invention provides a soft polyurethane foam obtained by foam molding a foaming stock solution containing a polyol, a polyisocyanate, a foaming agent, and a catalyst. The polyol includes a polyether polyol A having a weight average molecular weight (Mw) of 3,000 to 8,000 and 3 to 4 functional groups and a polyether polyol B having a weight average molecular weight (Mw) of 1,000 to 4,000 and 2 functional groups. The polyisocyanate includes diphenylmethane diisocyanate.
