Naphthalene based superplasticizer (sodium naphthalene sulfonate formaldehyde condensate) and some other chemical admixtures play an important role in modern concrete materials and technologies. 

In the 1930s, it was discovered that mixing sulfite pulp waste liquid into concrete can improve the workability of the mixture, and the strength and durability of concrete can also be improved. In 1935, an American first developed a water reducer with lignosulfonate as the main component. 

Dispersant MF is the formaldehyde condensation products of methyl naphthalene sulfonic acid sodium, mainly as the dispersant and the filler of reducing dye and disperse dyes, is mainly used in disperse dyes, processing agent and dispersant when reducing dye grinds, and performance is better than dispersant N.

Dispersing agent NNO, also called diffusing agent NNO, dispersant NNO, chemical name: sodium naphthalene sulfonate formaldehyde condensate.
