diaper super absorbent polymer

Diaper super absorbent polymer (or SAP) is a synthetic polymer primarily used as a water-absorbent material due to its unique property of absorbing large amounts of water relative to its mass. The use of diaper super absorbent polymer is an innovation, especially since it was applied to diapers decades ago. It is now widely used in baby diapers, incontinence products and sanitary napkins.
