Superabsorbent

SINOFLOC superabsorbent polymers (known as SAP) are water-insoluble polymer, cross-linked copolymer of acrylic acid. It is in the form of white, odourless granules. This water-absorbing polymer is produced by acrylic acid and a cross-liner solution through polymerization. This product has the character of superabsorbent which makes this material could absorb and retain water of hundreds of times of its weight shortly. Moreover, this product is able to hold absorbed water even against pressure.

 The characters make superabsorbent polymers (SAP) widely used in following fields:
  • Baby Diaper and Adult Diaper
  • Sanitary Napkin
  • Nursing Pad
  • Water Retaining Agent for Agriculture
  • Cable and Expanding Rubber
  • Plugging Agent
  • Concrete Curing

As one of the leading superabsorbent suppliers in China, SINOFLOC product has been widely used as aqueous absorbent for diapers, adult hygiene products and other similar applications.

Product Safety

Superabsorbent has been widely tested and is considered to be non-toxic by ingestion or application to the skin and not irritating or sensitising to the skin. Testing against various ecological indicator organisms indicates that the material does not represent an environmental hazard.

FAQ
What Kind of Superabsorbent Polymers (SAP) We Provide?
We have the Sodium based SAP and the Potassium based SAP.
What's the Difference for These Two Types of Superabsorbent Polymers (SAP)?
Firstly, the production technic for Sodium based SAP and Potassium based SAP is very different. 
And as they contain different functional groups, it works for different applications.
For example, Sodium based SAP used for producing personal sanitary products, liker diapers. And Potassium based SAP is widely used for agricultural industrial. 
What IS the Mechanism of Application Superabsorbent Polymers (SAP)?
Usually, the SAP polymer has a molecular backbone with Sodium or Potassium, when added to water, the neutralization start immediately across the diffusion gradient, the water molecules are drawn into the polymer network and locked within the polymer structure which is built by the SAP molecular chains (hydrogen bondings).
How SAP Expands to a Bigger Particular After Absorbing Water?
As the water is locked within the polymer structure, there is a force to straighten the SAP molecular chains, however, the molecular chains are cross-linked together, in the end, all forces reach a balance, the structure is still there while the particular size expands as the water absorbed in.
What're the Main Specifications of Superabsorbent Polymers (SAP)?
Following are the main specifications:
Absorption in 0.9% Nacl: 
0.9% NaCl solution could simulate human sweat, urine and blood, so this parameter is very important for producing diaper, nursing pad, and sanitary napkin
Why Potassium Based SAP Is More Popular in Agricultural Use?
As the sodium salts would make the soil harden after a long term use, while potassium salts won’t and potassium is also the necessary element for growing plants, it’s received a warm welcome from the markets.
Instructions

Retention Capacity after centrifugation

This test simulates when the diaper, sanitary napkin user is doing most kindly of intense body movements and activities, and the results shows the performance of the diaper or sanitary napkin. 

Residual Monomer

Chemical safety reference

Absorption Under Pressure

This test simulates when the diaper, sanitary napkin users is sitting down or lying down, how is the performance.

Particle Size Distribution

The particle size and distribution is very important for the absorbent speed, the finer the faster, the evener the performance is more stable and the performance in the different areas of the same absorption is closer without obvious difference, and the quality is also more stable for different batches of the diapers or napkins.
