Sodium Persulphate is a specialty chemical compound having a variety of applications, including its role in the production of Super Absorbent Polymers (SAP). In this blog, we will explore the significance of Sodium Persulphate in SAP and its importance in the creation of diapers, which has revolutionized the baby care industry.
Understanding Sodium Persulphate
Sodium Persulphate having the chemical formula as Na2S2O8, is a strong oxidizing agent. Its key characteristics include high solubility in water and excellent stability at room temperature, which are pivotal for its role in SAP production.
The Role of Sodium Persulphate in SAP
Super Absorbent Polymers (SAPs) are water-absorbing materials capable of retaining large amounts of liquid relative to their mass. They have gained immense importance in various applications where moisture management is critical. SAPs are most prominently used in baby diapers, adult incontinence products, and feminine hygiene items, revolutionizing the comfort and convenience of these products.
The synthesis of SAP involves the polymerization of acrylic acid or acrylamide with a cross-linking agent. Sodium Persulphate, often used as an initiator, plays a vital role in this polymerization process.
Initiation: The polymerization process requires the formation of radicals to initiate the reaction. Sodium Persulphate is a potent radical initiator, that is, it can break down into sulphate radicals under the influence of heat. These sulphate radicals, in turn, initiate the polymerization of acrylic acid or acrylamide.
Cross-linking: To create an effective SAP, cross-linking is essential. Cross-linking agents connect the polymer chains, forming a three-dimensional network. The cross-linking agent, when activated by the radicals generated from Sodium Persulphate, ensures the SAP can absorb and retain liquid efficiently.

Controlling Properties: The amount of Sodium Persulphate used and the polymerization conditions can be adjusted to control the properties of SAP, such as absorption capacity and gel strength. This level of customization is crucial in tailoring SAPs for different applications.
SAP in Diapers
The most notable application of SAP is in the production of baby and adult diapers. SAPs brought about a significant transformation in diaper design and functionality.
Here’s how SAPs, with the assistance of Sodium Persulphate, have revolutionized the diaper industry:
Enhanced Absorption: SAPs can absorb and retain many times their weight in liquid. This means that diapers can stay dry for longer durations, reducing discomfort and the need for frequent changes.
Reduced Leakage: The superior liquid retention capacity of SAPs helps prevent leaks.
Thin and Comfortable Design: Because SAPs can absorb a substantial amount of liquid while remaining relatively thin, modern diapers are much more comfortable and discreet than their predecessors.
