Ethylene imine polymer is widely used in various industrial applications due to its versatile properties. It is commonly employed as a flocculating agent in water treatment processes, where it helps in the aggregation and removal of suspended particles, improving water clarity and quality. In the paper industry, it serves as a wet-strength additive, enhancing the durability and strength of paper products when exposed to moisture. Additionally, it is utilized in the textile industry as a dye-fixing agent, improving the color fastness of fabrics. The polymer also finds applications in the production of adhesives and coatings, where it enhances bonding strength and durability. In the field of agriculture, it is used as a soil stabilizer and in the formulation of controlled-release fertilizers, promoting efficient nutrient delivery to plants. Its ability to modify surface properties makes it valuable in the manufacturing of specialty chemicals and personal care products.
