Karishma is a hygroscopic additive that can be used for drying purposes because of its affinity towards water. It absorbs water vapor from the product. It can be named as a heart of dehumidifier dryer system for hoppers, molders etc. Most plastics can absorb 3 – 15 % of their dry weight whereas our Additive can absorb 20 – 40 %. In use it becomes saturated with moisture requiring it to be regenerated by heating it to drive off moisture. The drying process is called selective absorption and it can be repeated several times.
