Abstract:
A low-resilience polyurethane foam is produced by allowing a low-resilience polyurethane foam composition containing polyisocyanate (a), polyol (b), catalyst (c), and blowing agent (d) to react. The polyisocyanate (a) contains bis(isocyanatomethyl)cyclohexane, and the polyol (b) contains 5 to 30 mass % of polyol (b-1) having an average functionality of 1.5 to 4.5 and a hydroxyl number of 20 to 70 mgKOH/g, and 70 to 95 mass % of polyol (b-2) having an average functionality of 1.5 to 4.5 and a hydroxyl number of 140 to 300 mgKOH/g.
