●Overview

The particle size of sodium polyacrylate which used in sanitary napkins (and other absorbent hygiene products) is extremely crucial as it directly affects the absorption rate, reabsorption volume and comfort level of the product.

The sodium polyacrylate (SAP) used in sanitary napkins typically range from 200 mesh to 400 mesh. Modern high-end products achieve a "fast absorption, no leakage back, ultra-thin and soft" user experience through precise particle size control and layered design, ensuring that liquids are quickly absorbed and securely retained.

●Corresponding grades and characteristics

This application are mainly using sodium polyacrylate

SR610: The granular distribution is concentrated and the particle size are fine, which could bring comfortable experience
