What is SAP – superabsorbent polymers

What Is SAP?

Superabsorbent Polymer (SAP) is a revolutionary material capable of absorbing and retaining up to 300× its own weight in water and aqueous fluids—without ever releasing it. Ideal for any product designed to manage moisture, SAP delivers unparalleled dryness and containment in:

• Baby diapers and training pants

• Adult incontinence products

• Feminine hygiene pads and liners

How It Works

1. Molecular Network: SAP is typically made from sodium polyacrylate, formed into a three-dimensional network of long, coiled polymer chains.

2. Absorption & Gelation: When liquid contacts the granules or fibers, the chains uncoil and expand, trapping fluid in the microscopic spaces of the network.

3. Locked-In Performance: The absorbed liquid transforms SAP into a stable gel, preventing leaks even under pressure—far surpassing ordinary fluff or sponge materials.

Key Benefits

Proven Safety & Reliability

• Extensive Testing: SAP materials have undergone rigorous toxicological, medical, and clinical evaluations.

• Expert Endorsements: Pediatricians, dermatologists, and nursing professionals affirm SAP’s safety in personal-care applications.

• Environmental Mindset: Designed for disposable hygiene products, SAP contributes to cleaner, more sustainable care routines.

Our Manufacturing Process

1. Raw Ingredients: Acrylic acid, sodium hydroxide (or alternative neutralizer), water, and a dedicated cross-linking agent.

2. Polimerizzazione: These components react to form a hydrated gel of interlinked polymer chains.

3. Sizing & Finishing: The gel is dried, milled, and sieved to precise granule or fiber dimensions—and can be fine-tuned with additional cross-linking for custom absorbency profiles.
