摘　　要：利用1,1,1,3,3五-氟丙烷(HFC-245 fa)的环保、安全等优良特性,将其作为喷涂聚氨酯硬泡领域ODS发泡剂的替代品,通过原料的选择和配方的优化,解决了以HFC-245 fa作发泡剂带来的易挥发等技术难点,使HFC-245 fa发泡剂在聚氨酯喷涂领域中得到很好的推广应用。1,1,1,3,3-Pentafluoropropane（HFC-245fa） can replace ODS blowing agent duo to excellent performance such as environment protection, security and so on. The problem of fast volatility for HFC-245fa as a blowing agent was resolved by choosing of raw material, technology and formulation adjustment. HFC-245fa was used in spraying Polyurethane（PU） field with good results.
