Superabsorbent Polymers (SAP) 101 is an informational website focused on superabsorbent polymers, including sodium polyacrylate and potassium polyacrylate. It introduces SAP as a material that begins as a powder and swells into a gel when exposed to moisture, with the ability to absorb hundreds of times its own weight in water. The site organizes information through application guides, frequently asked questions, supplier resources, and a searchable knowledge base.

Its content explains several uses for SAP. As an absorbent, it can take up large quantities of inorganic liquids, particularly pure water. Potassium-based SAP is presented as a water-retaining material for plants. The site also describes applications in cable water-blocking tape and inflatable sandbags, as well as products such as ice packs, aromatic gels, and gel fire-extinguishing agents. Supporting resources include guides to SAP types and uses, information about suppliers, and material safety data sheets for sodium polyacrylate and potassium polyacrylate. Overall, SAP 101 serves as an educational and product-reference resource for people exploring the properties and applications of superabsorbent polymers.
