Super absorbent polymer(Sanitary napkin) (510521)
Details:

Chemical

Properties

 Acrylic acid copolymer with moderate crosslinking and partial neutralization.
Appearance
 White and tasteless granules.
Description 
 Super absorbent polymer(SAP), made of sodium polyacrylate and mainly applied to sanitary napkins, has a unique body structure and excellent hydrophilic groups. This ensures that it not only is insoluble in water but also absorbs several hundred times of water or several dozen times of physiological saline (body fluid) its own weight, and has excellent water retention. It also has quick liquid absorption speed, high pressurized absorption, good gel strength, good moisture resistance and so on. It is made with advanced technology to be low in monomer residue, nontoxic, odorless and non-stimulant to skin. It can also be completely degraded into small molecules such as water, carbon dioxide and so on.
