Used as a crosslinking agent in the production of polyurethane foams, enhancing foam stability and mechanical strength. Commonly applied in flexible and rigid foam formulations for insulation, automotive seating, and cushioning materials. Also serves as a catalyst and chain extender in polyurethane systems, improving curing efficiency and product durability. Its hydrophilic nature contributes to better flow and processing characteristics in resin mixtures. Additionally, utilized in personal care products as a stabilizer or viscosity modifier due to its solubility and mild reactivity.
