Properties

SAP is a cross-linked that can absorb and retain large amounts of liquid through its unique molecular structure. The following properties make SAP the preferred for manufacturing:

• High Absorption Capacity – Can absorb 55–65 g/per gram of SAP.

• Strong Retention – Maintains over 90% even under pressure.

• Fast Absorption Speed – Quickly captures to reduce surface wetness.

• Particle Size Control – Standard sizes (150–850 μm) suitable for production lines.

• Skin-Friendly & Safe – Non-toxic, non-irritating, and safe for baby and adult care products.

Application Mapping & Selection Guidance

Below is practical guidance (trade-oriented) to help procurement select appropriate SAP grades. Final grade selection should be validated with onsite trials.

• Baby Diapers (mass market)
  Recommended: medium particle size (200–600 μm), absorption ≥ 50 g/g, balanced retention. Benefits: stable dosing on high-speed lines, good gel strength to prevent gel blocking.

• Premium Baby Diapers
  Recommended: high-absorbency grade (≥ 60 g/g), optimized gel strength and lower re-wet. Benefits: fewer core materials required, improved dryness and comfort.

• Sanitary Napkins / Panty Liners
  Recommended: finer particle size (< 300 μm) for even distribution and reduced surface granularity. Benefits: thinner structure, uniform distribution.

• Adult Incontinence Products
  Recommended: larger particle or high-capacity grades for extended retention and long-duration dryness.

• Industrial / Pet Pads
  Grades optimized for cost-efficiency and high capacity are available.

If you provide your target machine model, line speed (m/min), and dosing system, we will propose 2–3 candidate SAP grades and share sample guidance for machine tuning.

Specification & Typical Ranges

(Values are representative ranges offered through our supply channels. Final spec is confirmed per batch / source.)

Important: particle size distribution, bulk density and gel strength together determine dosing behavior, dust level, and machine handling characteristics. We provide technical matching to your production line.

Trade & Procurement Details (for Buyers)

To accelerate procurement decisions, we provide clear, buyer-oriented terms

• Sample policy: 1–2 kg samples available for qualified buyers; commercial samples and paid sample shipments are handled case-by-case.
• Typical MOQ: For international shipments, standard MOQ is typically 1 metric ton (MT) / 1000 kg or as agreed (we can consolidate multiple brands). Smaller pilot orders may be arranged depending on supplier and stock.
• Packaging: 25 kg kraft bags (standard), 500 kg jumbo bags (for bulk), or private-label packing on request; palletized export packing available.
• Lead time: Typical lead time 7–21 days after order confirmation, depending on brand source and stock; expedited shipping can be arranged for urgent needs.
• Payment terms: T/T, L/C at sight, or other mutually agreed terms.
• Export documentation: COA (Certificate of Analysis), MSDS/TDS, packing list, commercial invoice, and any required export certificates are provided.
• Quality control: Pre-shipment inspection, batch COA verification, and sampling upon request. We can coordinate independent third-party inspection if required.

FAQ

Q1: What is diaper absorbent?
A1: Refers mainly to SAP and fluff pulp, which together form the absorbent core of diapers and hygiene products.

Q2: Is SAP the same?
A2: Yes. SAP with the ability to absorb and lock liquid, making it the most important.

Q3: What is polymer used for?
A3: Used in 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).
