Definition and Properties of Polyether Polyols 2024-09-11
Polyether polyols are synthesized by the addition polymerization of initiators (compounds containing active hydrogen groups) with epoxyethane (EO), epoxypropane (PO), epoxybutane (BO), etc. in the presence of catalysts. It is an oligomer with an ether bond (- R-O-R -) in the main chain and more than 2 hydroxyl groups (- OH) in the end or side groups.
Storage and Safety of Polyether Polyols 2024-09-11
Polyether polyol products are generally packaged in clean, dry, sealed, and leak free galvanized iron drums. Protect from direct sunlight and rain during storage, and keep away from sources of fire and heat. The storage temperature should not exceed 70 ℃ to prevent moisture absorption and oxidation.
The use of polyether polyols 2024-09-11
Polyurethane material: polyether polyol is an important raw material for preparing polyurethane foam, polyurethane adhesive, polyurethane adhesive, polyurethane elastomer and other polyurethane materials. These materials are widely used in fields such as refrigerators, freezers, refrigerated trucks, insulation panels, and pipeline insulation.
The synthesis method of polyether polyols 2024-09-11
The synthesis of polyether polyols is mainly based on ring opening polymerization reactions. The specific process includes:
