Poly(propylene glycol) bis(2-aminopropyl ether)
High Reactivity: The terminal amine groups offer high reactivity, which significantly enhances the material’s performance across diverse applications.
Versatile Applications: It is utilized in polyurethane injection molding, polyurea spraying, epoxy curing, and as a scavenger in gasoline treatment.
Soft Polyether Backbone: The flexible polyether backbone contributes to improved material flexibility and compatibility during processing.
Water Solubility: It demonstrates water solubility (100g/L at 20°C), supporting its use in a wide range of aqueous and industrial chemical processes.
Amine-Terminated Polyether (ATPE) describes a class of polyolefin-based materials featuring a flexible polyether main chain terminated with primary or secondary amine functional groups. The combination of a soft polyether structure and the elevated reactivity of the terminal amine hydrogens provides ATPE with distinct advantages over conventional polyethers, particularly in advanced material processing. The amine groups contribute significantly to enhancing the performance and characteristics of novel materials.
These compounds are frequently employed in reactive injection molding of polyurethanes, spray-applied polyurea systems, epoxy curing agents, and as scavengers in gasoline treatment. The multifunctional nature of ATPE supports its use across industries where tailored material properties are essential.
