摘要： The present invention, which is characterized by the employment of blowing agents comprising fluorinated ethers with a boiling point in the range of from about 0 DEG C to 75° C., pertains to a composition of microcellular polyurethane, a method for preparing the same, and its use in manufacturing shoe materials. Compared to shoe soles made from traditional microcellular polyurethane, in particular those made using 1,1,1,2-tetrafluoroethane (HFC 134a) as the blowing agent, the polyurethane shoe soles prepared according to the present invention exhibit similar shrinkage characteristics, and their linear shrinkage is compatible with the current processing conditions, thus can replace traditional blowing systems comprising 1,1,1,2-tetrafluoroethane (HFC 134a) in shoe manufacturing without the need of changing molds. On the premise of being more environmental-friendly, the present invention also effectively saves production cost for shoe manufacturers.
