الوصف

Polymer crystals are one of those special items that are almost magical. Add water to the white crystalline flakes and they absorb many times their size in the polymeric gel that forms. One pound of the crystals holds about 50 gallons of water! The gel that forms swells by absorbing 30 grams of water for each gram of the crystals. Construction workers, bicyclists and motorcyclists may be seen wearing cloth headbands or wearing a cloth collar around their neck. The crystals are sewn into a pouch in the cloth. The cloth item is then soaked in water for several hours. A tiny handful will swell up to many times its size and provide moist evaporate cooling. Florists also use polymer crystals as a dirt-free way to store water and to keep cut flowers fresh for a long time. It takes about 45 minutes to hydrate the typical headband or collar. Refrigeration ahead of time is not necessary, but it does help extend the cooling time. The same polymer crystals can be rehydrated many times. Soil vigor (tm) eco- friendly nontoxic. Reducing outdoor water usage by 50%, soil aeration promoting healthy plants (indoor & outdoor), garden, trees and lawns and save on labor.
