Upgrade Your Supply with Smart SAP Technology

Tired of complaints about leaks and discomfort from traditional underpads? Switch to high-absorbency SAP (Super Absorbent Polymer) cores. They lock in moisture instantly, keeping skin exceptionally dry and preventing leaks. This means higher customer satisfaction, fewer returns, and a stronger brand reputation for your business.

As a professional manufacturer, we offer reliable OEM/ODM services and bulk supply. Ready to upgrade your product line? Contact us for samples and competitive quotes today.

Detailed comparison table
Feature Dimension	Nursing pads containing superabsorbent polymers	Nursing pads without polymers (traditional fibers)
Core Absorbing Material	Superabsorbent polymer (SAP) + fluff pulp	Fluff pulp, cotton, non-woven fabrics, etc.
Absorption principle	Chemical water absorption (locks water molecules firmly within the polymer mesh)	Physical water storage (liquid is stored in the fiber gaps)
Absorption rate and amount	Extremely fast, with a huge absorption capacity. It can quickly absorb liquid and diffuse it throughout the entire absorption layer.	It is relatively slow, and the absorption capacity is limited. It easily reaches local saturation, and then the lateral diffusion of the liquid is slow.
Water retention and reverse osmosis	It has excellent water retention with virtually no backflow. The surface can remain dry for a long time.	It has poor water retention; when subjected to pressure (such as when a person lies down), the liquid is easily squeezed out, resulting in severe backflow and a feeling of dampness on the skin.
Thickness and Structure	Even after absorbing a large amount of liquid, it remains thin and light because the liquid is fixed by the gel and does not become fluffy.	After absorbing liquid, it becomes thick, fluffy, prone to clumping, and deformed.
Skin dryness	Very high, effectively keeps skin dry and prevents bedsores and maceration.	Low humidity levels mean that prolonged contact between the skin and a damp surface can easily lead to problems such as rashes and diaper rash.
Odor control	Locking in the liquid and reducing the surface area of the liquid in contact with air helps to suppress the emission of odors such as ammonia.	Liquids tend to linger on surfaces, making it easier for odors to be generated and dissipated.
Cost and Price:	The unit price is relatively high because the core material (polymer) is expensive.	The unit price is low because the material cost is low.
Environmental protection	The material is not easily degraded and expands in volume after absorption, taking up a large amount of space in landfills. However, this can be partially offset by the reduced frequency of replacement.	Most of them are made of natural fibers, which are relatively easier to degrade, but their poor absorption and leak-proof properties may lead to more replacements and waste.
Applicable Scenarios	This condition is suitable for patients with moderate to severe incontinence, prolonged bed rest, significant postoperative exudation, require long-term protection, and have high requirements for keeping the skin dry.	Mild incontinence, extremely limited budget, or as a temporary or supplementary pad (such as a pet pad or item stain protector).
Advantages and disadvantages	The disadvantage is that the surface of polymers is relatively rough.	Advantages: Soft surface, suitable for babies.
