Hydrogel – 500g Bag

This high‑performance non‑toxic hydrogel powder is capable of absorbing up to 500 times its own weight in water, making it a versatile material for science experiments, demonstrations and practical applications. Commonly used in products such as nappies, water‑retaining gels and long‑lasting plant irrigation systems, this hydrogel offers a safe and engaging way to explore water absorption and polymer chemistry.

When mixed with water, the powder rapidly transforms into a gel‑like substance that traps and holds large quantities of liquid. This makes it ideal for investigations into osmosis, super‑absorbent polymers, moisture retention and material science.

Supplied in a generous 500g bag, this hydrogel provides enough material for repeated classroom demonstrations or large‑scale experiments.
