Polymers are small dry crystals that act like super sponges.
They can be starch based, polyacrylates, or polyacrylamides, that soak up liquids. One teaspoonful of dry polymers will absorb an entire glass of water in about 20 minutes and become a jelly-like mass of globules. They are also used in medicine, paper production, disposable diapers, food packaging, horticulture and oil drilling. Absorbent polymers not only help conserve natural resources, they also save you time, energy, fertilizer, water and money. They help protect the environment by preventing fertilizer nutrient leaching in irrigation runoff.
