This remarkable polymer can absorb hundreds of times its weight in water. Sodium polyacrylate is also widely used in common hygiene products such as paper diapers and sanitary towels, making it a non-toxic, harmless, and dissolvable material.<\/p>\n<h3>How to Judge the Quality of Sodium Polyacrylate<\/h3>\n<p>To evaluate the quality of sodium polyacrylate in ice packs, consider the following parameters:<\/p>\n<ol>\n<li>Absorption: How much liquid the polymer can absorb.<\/li>\n<li>Absorbent Rate: How quickly the polymer absorbs liquid.<\/li>\n<li>Absorption Under Pressure and Retention Capacity After Centrifugation: Ensures that the gel effectively locks in water.<\/li>\n<li>Particle Size Distribution: The consistency of the polymer particles.<\/li>\n<\/ol>\n<h3>About GELSAP<\/h3>\n<p>As a professional manufacturer of <strong><a href=\"https:\/\/saphydrogels.com\/en_ca\/super-absorbent-polymer\/\">gel ice pack contents<\/a><\/strong>, GELSAP offers high-quality sodium polyacrylate.
