Sodium polyacrylate
Sodium polyacrylate is a water absorbing polymer that is derived from acrylic acid, a colorless, odorless, and slightly soluble liquid. Sodium polyacrylate is used in a variety of applications, the most popular of which is its use in diapers to absorb and retain urine. The polymer can absorb up to 300 times its weight in water, making it an extremely efficient means of moisture control. In addition to its use in diapers, sodium polyacrylate is also used in disposable training pants, adult incontinence products, and feminine hygiene products.
The polymer was developed in the 1970s by three scientists, Dr. Samuel Smith, Dr. Jerome Ghost, and Dr. David Pearce. The three scientists were working on a project for the United States Air Force to find a way to create a synthetic absorbent that could be used in airtight suits to protect pilots from hypoxia. Sodium polyacrylate was discovered as a result of their research, and the polymer was eventually commercialized for use in diapers and other absorbent products.
The polymer is manufactured in a number of different forms, including a powder, granules, and a liquid. The powder form is the most popular, as it can be easily transported and stored. The powder is mixed with water to create a solution that can be used in absorbent products. The polymer is also non-toxic, which makes it a safe alternative to other absorbent materials such as cotton and rayon.
Sodium polyacrylate is an effective means of moisture control and is safe for use in a variety of absorbent products. The polymer is efficient at absorbing and retaining urine and other body fluids, making it an ideal choice for diapers, training pants, adult incontinence products, and feminine hygiene products.
