Sodium polynaphthalene formaldehyde sulfonate is used as a disintegrator/dispersant, emulsifier, and emulsion stabilizer. It is commonly found in speciality products.

In agriculture, sodium polynaphthaleneformaldehyde sulfonate is used as a dispersant and dissolver of pesticides. It is very stable even in very hard water and retains its properties at high mineralization.

In the construction industry it is used as a product to reduce scattering and friction in cementation processes. It is most commonly used in water and oil well cementing applications where heat resistance, uniform distribution and lower pumping resistance are important. It can also be used as an admixture to reduce the water content in concrete. Recommended concentrations range from 0,1 to 1% of the dry weight of cement.

In textiles, dyeing, printing, naphthalene sulfonic acid polymer with formaldehyde sodium salt is used as a dispersant, smoothing agent to make the ink homogeneous. It has an excellent ability to protect the colloid (does not alter the behavior of fine particles), is non-volatile, non-foaming. Structure affinity to proteins and polyamide fibers; no affinity to cotton fibers and therefore aids the adhesion of pigments and dyes to cotton fibers.

In the manufacture of paints, sodium poly[(naphthalene formaldehyde) sulfonate] is used as a distributor of paint components, as a levelling agent in disperse paints, in the manufacture of reactive paints, in washing inks. Painted surfaces can be sanded and scrubbed.
