Sodium poly[(naphthaleneformaldehyde)sulfonate] is widely used as a dispersant in various industrial applications. In the construction industry, it is added to concrete mixtures to improve workability and reduce water content, enhancing the strength and durability of the final product. In the textile industry, it acts as a dye dispersant, ensuring even color distribution and preventing clumping during the dyeing process. Additionally, it is employed in the production of ceramics and paints, where it helps stabilize particles and improve the consistency of the formulations. Its ability to prevent sedimentation and agglomeration makes it valuable in water treatment processes as well, where it aids in the dispersion of suspended solids.
