Properties of Absorbent Polymer
SAP is a cross-linked polymer that can absorb and retain large amounts of liquid through its unique molecular structure. The following properties make SAP the preferred absorbent polymer for diaper manufacturing:
-
High Absorption Capacity – Can absorb 55–65 g of liquid per gram of SAP.
-
Strong Retention – Maintains over 90% of liquid even under pressure.
-
Fast Absorption Speed – Quickly captures liquid to reduce surface wetness.
-
Particle Size Control – Standard sizes (150–850 μm) suitable for diaper production lines.
-
Skin-Friendly & Safe – Non-toxic, non-irritating, and safe for baby and adult care products.
Applications of Diaper Polymer
Super Absorbent Polymer is used in a wide range of absorbent hygiene products, each requiring specific performance levels:
-
Baby Diapers – Provides long-lasting dryness, preventing leaks and keeping babies comfortable.
-
Adult Incontinence Products – Ensures security and dignity for adults with high absorption needs.
-
Sanitary Napkins – Improves liquid retention and comfort in feminine hygiene products.
-
Pet Training Pads – Delivers high absorbency and odor control for pet care applications.

FAQ
Q1: What is diaper absorbent material?
A1: Diaper absorbent material refers mainly to Super Absorbent Polymer (SAP) and fluff pulp, which together form the absorbent core of diapers and hygiene products.
Q2: Is SAP the same as absorbent polymer?
A2: Yes. SAP is a type of absorbent polymer with the ability to absorb and lock liquid, making it the most important diaper polymer.
Q3: What is diaper polymer used for?
A3: Diaper polymer, or SAP, is used in baby diapers, adult incontinence pads, sanitary napkins, and pet pads for superior absorption and retention.
Q4: How to choose the best SAP for diaper production?
A4: Consider absorption capacity, retention, particle size, and speed of absorption. Choosing the right grade depends on the product type (baby, adult, feminine care, or pet care).
