Sodium polyacrylate, chemical formula (C3H3NaO2)n, is a new type of functional polymer material and important chemical product. The solid product is white or light yellow block or powder, and the liquid product is colorless or light yellow viscous liquid. From acrylic acid and its esters as raw materials, obtained by aqueous solution polymerization. Odorless, soluble in sodium hydroxide aqueous solution, and precipitated in aqueous solutions such as calcium hydroxide and magnesium hydroxide. It is often used as a water treatment agent, brine refining and latex thickening, and can also be used for food thickening and emulsification.

Mainly used as a viscosity reducer for drilling fluids, suitable for water-based drilling fluid systems, can reduce filtration loss, improve the quality of mud cakes, and have a certain ability to resist temperature and salt. It can be used directly or formulated into an aqueous solution. In addition, it is also used as a scale inhibitor and dispersant for circulating cooling water systems such as power plants, chemical plants, fertilizer plants, oil refineries and air conditioning systems.
Sealed at room temperature, dark, ventilated and dry place.
