摘要
成功地制备了一种用于无ＣＦＣ发泡的新型硬泡聚醚多元醇，该聚醚可广泛地用于ＨＣＦＣ１４１ｂ和环戊烷作为发泡剂的硬泡组合料中，用该聚醚制备的硬质聚氨酯泡沫具有高强度、低导热系数、高尺寸稳定性等优异性能。目前该产品已正式投入生产，随着国内聚氨酯工业的发展，它将会得到广泛应用。
A CFC - Free rigid foam polyether polyol has been pepared successfully. It can be used in varied fields which use HCFC141b and cyclopentane as blowing agent, the foam manufactured by this polyol gains excellent excellent, such as high strength, loW heat conductive co -- efficient and high dimensional stability, thes polyol has ben put into real production. Following the development of polyurethane industry, mis rigid foam polyether polyol will be widely used in near future.
