Our process is rigorously scientific, and our formula is deliberately simple: water and sodium polyacrylate. Nothing else.
The vehicle: water
Water carries the cold. When it freezes inside the pouch, it stores a large amount of cooling energy.
The engine: sodium polyacrylate
This polymer turns the water into a stable gel. It slows thawing, stops the water from sloshing or leaking, and lets the pack release its cold evenly.
The result
Constant cold and non-toxic protection for your sensitive shipments. The formula is completely safe and certified non-toxic, so you can forget unnecessary chemicals.
