The material for gel ice packs
Sodium polyacrylate, also called superabsorbent polymer, is a non-toxic, eco-friendly polymer material. It can absorb plenty of water and turn to water gel form.
Sodium polyacrylate also referred to as Slush Polymer has the capacity to absorb and retain liquid in large quantities relative to its own mass. It is a white granular or powder solution material which can absorb liquid a hundred times its weight and when it does, it locks water firmly.
Gel ice pack also called cold pack, is the substitute product for the traditional ice bag.
