ATPE (poly(propylene glycol)bis(2-aminopropyl ether)) is a class of polyolefin compounds with a flexible polyether backbone, terminated by primary or secondary amine groups. Because the molecular backbone is a flexible polyether chain, and the hydrogen at the end of Poly(propylene glycol)bis(2-aminopropyl ether) is more reactive than the hydrogen at the end of the hydroxyl groups in the polyether, Poly(propylene glycol)bis(2-aminopropyl ether) can effectively replace polyether in some material processing applications and improve the performance of new materials. It is widely used in polyurethane reaction injection molding materials, polyurea spraying, epoxy resin curing agents, and gasoline detergents.
