Poly(propylene glycol) bis(2-aminopropyl ether)
High Reactivity: Featuring highly reactive terminal amine groups, this product delivers a substantial boost to overall performance in a wide variety of applications.
Wide Usability: It is widely applied in polyurethane injection molding, polyurea spraying, epoxy curing systems, and also acts as an effective scavenger in gasoline refining.
Flexible Polyether Chain: Its soft, flexible polyether structure greatly improves the flexibility and compatibility of the material during production and processing.
Water Solubility: It dissolves readily in water (100g/L at 20°C), supporting its use in numerous water-based formulations and industrial chemical applications.
Amine-Terminated Polyether (ATPE) refers to a group of polyolefin-derived compounds that possess a flexible polyether backbone capped with primary or secondary amine functional groups. The integration of a soft polyether framework together with the high reactivity of hydrogen atoms on the terminal amines gives ATPE notable benefits over traditional polyether products, especially in the field of high-performance material manufacturing. These amine moieties play a key role in elevating the overall performance and functional properties of advanced new materials.
These substances are widely used in polyurethane reactive injection molding, spray polyurea systems, epoxy curing applications, and as scavenging agents in gasoline processing. The multifunctional characteristics of ATPE enable its adoption across various industrial sectors that demand customized material performance.
