[0002] Polyester polyol is one of the main raw materials of polyester polyurethane. It can be divided into aliphatic polyol and aromatic polyol according to whether it contains benzene ring. Polyester polyol is not a dangerous transport item. The materials of storage and transportation containers can be carbon steel, aluminum, stainless steel, polyethylene or polypropylene. Liquid polyester occasionally becomes turbid when stored at low temperature for a long time. This phenomenon can be eliminated by heating at about 80℃ for a short time without affecting the quality. Polyester polyol is easy to absorb moisture. Moisture in the atmosphere should be avoided during storage and transportation. In order to reduce the reverse reaction, the temperature should not exceed 120℃. The product should be stored in a sealed barrel isolated from air at room temperature, or stored in a container heated and insulated at 70-110℃ and filled with nitrogen; at the same time, because the impurities in polyester polyol may promote the occurrence of oxidation reaction in the form of catalyst, it will cause the polyester polyol to discolor due to oxidation.
