Sodium polyacrylate, also known as water lock, is a sodium salt derived from polyacrylic acid. Its exceptional water absorption capacity, up to 200 to 500 times its weight, makes it a highly versatile material used across various industries.
It can be categorized into three major grades: Hygiene grade, Agriculture grade, and Industry grade, each serving specific purposes such as absorbing, retaining, or blocking liquids.
Applications and Main Models:
For Diapers: Sodium polyacrylate is a widely used surfactant in diapers, providing water repellency, moisture retention, anti-blocking, and stain resistance properties. It enhances diaper elasticity, improves wetness absorption speed, and reduces stickiness. Additionally, it offers antibacterial, anti-oxidation properties, protecting the skin and enhancing diaper performance.
For Lady Sanitary Napkins: SAP used in sanitary napkins boasts fast blood absorption, high absorption capacity, good gel strength, and moisture resistance. Its strong absorption and water retention capabilities keep users dry and comfortable.
