Where is polyether used? Polyether polyol is an important derivative of propylene oxide and one of the main raw materials for polyurethane synthesis. In the presence of propylene oxide, propylene oxide or propylene oxide as the starting material, the polymer is prepared.
Polyether polyols series products are mainly used in the preparation of rigid polyurethane foam, and are widely used in fridge, freezer, refrigerated vehicle, heat insulation board, pipe insulation and other fields. The product with low thermal conductivity and good dimensional stability is also an important raw material for compounding polyether. The production of polyether polyols in polyurethane industry is mainly used in polyurethane foam plastics. The main varieties are polyoxypropylene polyols and polytetrahydrofuran polyols. Today, we will learn about the precautions in the use of polyether polyols
(1) Do not come into direct contact with the air due to its hygroscopicity.
(2) Avoid open fire, should avoid heating in the air for a long time, especially polyether polyol infiltrated insulation materials, clothing and so on often will naturally fire, should pay attention to.
