SAP  - Super Absorbent Polymer 

Ultra-Fast Locking |  Safe  |   High Multiplier

This product is a new functional polymer material, with its core chemical component being low cross-linked sodium polyacrylate. Relying on super-hydrophilic groups and a unique three-dimensional molecular network structure, this material can absorb and lock in a large amount of liquid in an extremely short time. It can not only absorb hundreds to 1,000 times its own weight in deionized water, but also dozens of times its own weight in physiological saline. Once it absorbs water, it rapidly expands into white crystal particles. Even under external pressure, it firmly locks the water within the gel network, making it extremely difficult to separate the water. As a new generation of eco-friendly material, it is totally non-toxic, harmless, and non-polluting, making it an indispensable core raw material for manufacturing high-quality disposable hygiene products.

 Product Highlights 

• Instant Gelation, Liquid Locking and Leak Prevention: SAP quickly turns liquid into solid gel, which not only greatly reduces the risk of liquid spills but also effectively helps control odors, enhancing the user experience.

• Specifically Developed for Hygiene Products, Excellent Quality: Specially developed for the core manufacturing of high-end disposable hygiene products (such as baby diapers and sanitary napkins). Its outstanding absorption and water retention properties are the key to achieving the perfect combination of "thinness" and "high capacity" in hygiene products.

• Super-Hydrophilic Network Structure: Relying on super-hydrophilic groups and a unique molecular structure, the product can rapidly absorb water in a very short time and retain moisture weighing several hundred or even 1,000 times its own weight, with performance far exceeding traditional absorbent materials.

• Elevating Medical and Nursing Hygiene Standards: In medical care scenarios, this material can rapidly solidify liquids, helping to minimize cross-contamination and significantly improving hygiene and convenience during patient care.

• Ultra-Fast Absorption and Strong Water-Locking: Features an extremely fast water absorption speed, instantly converting into a gel state upon contact with liquid, effectively preventing side leakage and rewetting. It possesses superior water retention capability; after forming a stable hydrogel, it is difficult to lose water even under pressure or heat, ensuring the surface of the end product remains persistently dry.

• Nontoxic, Safe, and Eco-friendly: As an environmentally friendly polymer material, the product is non-toxic, tasteless, harmless, and non-polluting, and is safe and reliable for users' skin. Some product series are biodegradable, effectively reducing environmental burden.

• Long-Lasting Performance Stability: It has a long service life and extremely stable performance. Even in extremely dry or complex environments, the material will not deteriorate, decompose, or experience performance degradation, ensuring the reliability of the end product throughout its shelf life.

• Flexible Customization: We provide tailor-made solutions based on specific customer requirements. Whether it is adjusting the absorption capacity, absorption speed, or particle size, we can precisely match the design specifications of different end products.

Technical Specifications

Note on Mesh Count: Refers to the size or fineness of the material's grain, i.e., the number of holes in the sieve within 1 square inch (25.4mm × 25.4mm). For example, 20 mesh means there are 20 holes per square inch; 100 mesh means there are 100 holes per square inch. The higher the number, the finer the grain size; the lower the number, the coarser the grain size. We offer a variety of mesh sizes for you to choose from to meet different process requirements.
