Manufacturer Good Price D2000 CAS: 9046-10-0
Amine-TerminatedPolyether (D2000) is a class of polyolefin compounds with a soft polyether backbone, capped by primary or secondary amine groups. Because the main chain of the molecule is a soft polyether chain, and the hydrogen on the terminal of polyether amine is more active than the hydrogen on the terminal hydroxyl group of polyether, therefore, polyether amine can be a good substitute for polyether in some material processes, and can improve the application performance of new materials. D2000 are widely used in polyurethane reactive injection molding materials, polyurea spraying, epoxy resin curing agents and gasoline scavengers.
