SOFT URETHANE FOAM AND SEAT PAD USING SAME

WIPO Patent Application WO/2016/031380

A1

Provided are: a soft urethane foam of low density and good moist heat compressive residual stress that maintains good moldability even as metal corrosion by the polyol mixture is low; and a seat pad using same. A soft polyurethane foam obtained by injecting a foaming stock solution containing (A) a polyol component, (B) a polyisocyanate component, (C) a foaming agent, (D) a catalyst, and (E) a foam stabilizer into a mold cavity and foaming and curing same, wherein: the polyol component contains a polyether polyol, a polymer polyol, and a 200-2000 mg KOH/g hydroxyl value terminal primary hydroxyl group-containing compound and/or short chain polyol obtained from an ethylene oxide addition reaction; and the catalyst has a resinification catalyst as the main component.
