• Application

  Polyurethane hydrogels, combining the advantages of both hydrogels and polyurethane, possess high mechanical strength and a wide range of performance control, making them widely used in biomedical and industrial fields. Among them, single-component polyurethane hydrogels with high water retention capacity are excellent polymer sand-fixing materials due to their low cost, convenient construction, and environmental friendliness, suitable for desertification control, slope ecological protection, and soil erosion prevention. The key to preparing polyurethane hydrogels lies in the synthesis of the polyurethane prepolymer; the structure and properties of the polyurethane prepolymer determine the performance of the resulting polyurethane hydrogel.;
