What is SAP in a Diaper?

In modern parenting, diapers are widely used in daily care for babies. In the core technology of diapers, an important ingredient is widely used, which is SAP (Super Absorbent Polymer). This article will introduce in depth the role, properties and application of SAP in diapers. Let us uncover the mystery of SAP in diapers!


What is SAP?
Super absorbent polymer (SAP) is a polymer compound with excellent water absorption performance. It is formed by introducing a cross-linking structure into the polymer chain. The characteristic of SAP is that it can absorb hundreds or even thousands of times its own weight in water and maintain the stability of its structure for a certain period of time.

The role of SAP
SAP plays a key role in diapers. It has the following important functions:
a. Absorbing urine: The main function of SAP is to absorb and fix urine. When urine contacts SAP, it quickly absorbs water and converts it into a gel-like substance, preventing urine from flowing back and effectively preventing leakage.
b. Reducing odor: SAP also helps reduce odor in diapers. It can capture harmful substances such as ammonia in urine, reduce the release of odor, and thus maintain a fresh environment around the baby.
c. Keep dry: SAP in diapers can quickly absorb moisture and lock it in the gel, effectively preventing the baby's skin from contacting urine for a long time, keeping the baby's skin dry, and reducing discomfort and rashes caused by moisture.


Properties of SAP

a. High water absorption: SAP is a material with extremely high water absorption. Due to its cross-linked structure, SAP can quickly absorb a large amount of water and maintain a gel state to prevent water from overflowing.
b. High stability: SAP can maintain the stability of its structure after absorbing water, and will not swell or decompose due to the large amount of water absorbed, thus ensuring the reliability and service life of diapers.
c. Safety: SAP is usually made of non-toxic and non-irritating materials and undergoes strict safety tests. Ensure that it is non-irritating to the baby's skin and meets relevant safety standards.


SAP application in diapers

SAP is widely used in the core part of diapers, usually in the absorbent layer of diapers. It exists in the inner layer of diapers in the form of particles or fluff. When the baby's urine contacts the surface of the diaper, SAP absorbs water and converts it into gel, quickly locking and fixing the urine. This design effectively maintains the baby's comfort and reduces the risk of leakage.

As an important component of diapers, SAP plays a role in comfort, dryness and reliability in the baby's life. Its high water absorption and stability ensure the absorption capacity and performance of diapers. At the same time, the safety of SAP also allows parents to use diapers with confidence and provide a better care experience for their babies. By understanding the role and properties of SAP, we can better understand and appreciate the progress of diaper technology and provide better protection for the growth of babies.
