Application

As a dispersant, Sodium Methacrylate can be used as an auxiliary material for coatings. It is a kind of polyanionic polymer dielectric and an important chemical product developed in modern times with a wide range of uses. It’s widely used in environmental protection, food, medicine, textile, water treatment, petrochemical, metallurgy and other sectors. Sodium polyacrylate includes water-soluble and water-swellable the two categories. Water-swellable sodium polyacrylate belongs to the category of super absorbent resin. Another type of water-soluble sodium polyacrylate has various properties due to its different molecular weight and is widely used in food, feed, textile, papermaking, water treatment, petrochemical, agriculture, forestry and horticulture, sanitation and other fields. Sodium polyacrylate is mostly obtained by polymerization of acrylic acid as raw material after neutralization with sodium hydroxide. We can also modify the properties of sodium polyacrylate by copolymerizing Sodium acrylate with other monomers, and synthesize sodium polyacrylate copolymer with special properties.
