What is jelly crystal?

Jelly crystals, also known as water crystals or polymer crystals, are superabsorbent polymers (SAPs) that have the ability to absorb and retain large amounts of water. They are usually made from polyacrylic acid or polyacrylamide, which are cross-linked to form a network of hydrophilic (water-loving) groups.

Jelly crystals are commonly used in various applications due to their unique properties, including:

- Absorbency: They can absorb and hold up to several hundred times their weight in water, turning into a gel-like substance.

- Water retention: Once absorbed, the water is held within the polymer's structure, preventing evaporation and allowing controlled water release over time.

- Swelling: When exposed to water, jelly crystals swell and expand significantly in volume, creating a bulky and absorbent material.

- Clarity and transparency: They are often transparent or translucent, allowing for visual observation of the absorbed water.

- Biodegradability: Some jelly crystals are biodegradable and environmentally friendly, breaking down over time without causing harm to the environment.

Applications of jelly crystals include:

- Soil amendment: In agriculture, jelly crystals can be mixed into the soil to improve its water retention capacity, reduce water evaporation, and provide a continuous source of moisture for plants.

- Nappy filling and hygiene: Jelly crystals are commonly used in baby nappies/diapers and adult incontinence products due to their high absorbency and gelling properties.

- Packaging and transportation: They can be used as cushioning and protective material for fragile items during shipping and storage, as they absorb and retain moisture and shock.

- Art and decorations: Jelly crystals find application in creating water-based sensory experiences and decorations. They are used in decorative vases, terrariums, and other artistic projects to add color, texture, and movement to liquid environments.

- Medical and pharmaceutical: In certain medical settings, jelly crystals may be used in wound dressings to control exudate and keep wounds moist.

Overall, jelly crystals serve as versatile and useful materials due to their superabsorbent and water-retaining properties. They have applications in various fields, including agriculture, hygiene, packaging, art, and healthcare.
