Low repulsion polyurethane foam and method for producing same

A low repulsion polyurethane foam is obtained by causing a low repulsion polyurethane foam composition containing a polyisocyanate (a), a polyol (b), a catalyst (c), and a foaming agent (d) to react. The polyisocyanate (a) contains bis(isocyanatomethyl)cyclohexane. The polyol (b) contains 5 to 30 ma...

Beschreibung
Zusammenfassung:	A low repulsion polyurethane foam is obtained by causing a low repulsion polyurethane foam composition containing a polyisocyanate (a), a polyol (b), a catalyst (c), and a foaming agent (d) to react. The polyisocyanate (a) contains bis(isocyanatomethyl)cyclohexane. The polyol (b) contains 5 to 30 mass% of a polyol (b-1) having an average functional group number of 1.5 to 4.5 and having a hydroxyl number of 20 to 70 mgKOH/g, and 70 to 95 mass% of a polyol (b-2) having an average functional group number of 1.5 to 4.5 and having a hydroxyl number of 140 to 300 mgKOH/g.
