In this paper, the hygrothermal aging experiments of polyurethane buffer materials for elevator were carried out for 5 days, 10 days, 15 days, 20 days, 25 days and 33 days. The quality change, hardness change, tensile strength and elongation at break of the test materials before and after the experiment were compared and analyzed. The results show that the aging process of polyurethane materials is accelerated by the humid and hot environment.
