Abstract

PURPOSE: To obtain titled foam whose starting urethane solution shows good metal mold temperature characteristics, by producing the foam from a specified polyhydroxy compound, a polyisocyanate, a blowing agent, a foam stabilizer and a catalyst.
CONSTITUTION: A soft polyurethane foam is produced from a polyhydroxy compound, a polyisocyanate, a blowing agent, a foam stabilizer, other adjuvants and a polyhydroxy compound. Said polyhydroxy compound comprises (A) a polyether- polyol, OH value 35W65mgKOH/g, ethylene oxide content 50W85wt%, and/or a polymer polyol obtained by grafting an ethylenically unsaturated monomer onto the polyether-polyol, (B) a polyether-polyol, OH value 27W45mgKOH/g, terminal primary OH content ≤75mol%, etc. and (C) a polyetherpolyol, OH value 45W65mgKOH/g, ethylene oxide content ≤25wt%, terminal primary OH content ≥50mol%, etc., in a weight ratio, (A):(B):(C) of 40:40:20W85:10:5.
