摘要： A polyurethane composition is provided. The polyurethane composition comprises (A) one or more polyurethane-prepolymers prepared by reacting at least one polyisocyanate compound with a first polyol component; and (B) a second polyol component; wherein at least one of the first polyol component and the second polyol component comprises an ester/ether block copolymer polyol synthesized by reacting a starting material polyether polyol with a C4-C20 lactone. The polyurethane foam prepared by using the polyurethane composition can achieve inhibited internal heat buildup, high thermal stability and superior tear strength. A polyurethane product prepared with said foam, a method for preparing the polyurethane foam and a method for improving the performance property of the polyurethane foam are also provided.
