Super absorbent polymer (SAP)
FN SAP-A26Hygiene grade, Agriculture grade and Industry grade
liquid form of superabsorbent polymer (SAP) created using emulsion or solution polymerization, typically used to coat substrates or solidify liquid waste, rather than in its common dry powder/granular form

| Main Application | Hygiene Products: The largest application is in disposable personal hygiene items such as baby diapers, adult incontinence products, and feminine hygiene pads, where they effectively absorb and lock away fluids. Agriculture and Horticulture: Used as a soil conditioner or water-retaining agent to improve soil water-holding capacity, reduce irrigation frequency, minimize transplant shock, and enhance crop yield, particularly in arid areas. Industrial Uses: Spill Control and Waste Management: The emulsion or powder can be used to solidify aqueous chemical leaks, biohazard waste, and other liquid spills for safer and easier disposal. Dewatering: Used to remove water from fuels (e.g., aviation fuel, diesel), sludge, or sediment. Construction: Incorporated into cement and mortar as an internal curing agent and to create self-healing concrete that can seal its own cracks. Water Blocking: Applied in power and communication cables to prevent water penetration and damage. Biomedical Field: Employed in highly absorbent wound dressings, surgical pads, and controlled drug delivery systems due to their biocompatibility and ability to maintain a moist healing environment. |
| Characteristics | Composition: Most superabsorbent polymers are made of sodium polyacrylate (poly-acrylic acid sodium salt). Agricultural-grade variants often use potassium polyacrylate, which is less harmful to plants. Mechanism: The polymer chains contain numerous hydrophilic (water-attracting) groups. When water is introduced, an osmotic pressure difference draws the water into the polymer network, causing it to swell into a gel and trapping the liquid inside. Form: While most commercial SAPs are sold as powder or granules, the emulsion format is a liquid slurry or solution that can be diluted and applied directly as a coating to a substrate, and dried afterwards. Performance: The absorption capacity can be hundreds of times its mass in pure water but drops significantly in saline solutions (e.g., urine, blood, or saltwater) due to the ionic concentration. |
