Chill Wrap™ Ice Replacement (or gel ice or slicka pad or coolant) uses the water-loving (hydrophylic) action of a special salt in a spectacular way.
It works by:
- Absorbing water through the fabric surface
- Trapping the water in a damp gel that can’t escape through the fabric
- Freezing the gel to make ice
- Because of the cellular structure the ice remains flexible
- It can’t leak when thawed because the gel particles are too big to fit through the fabric.
