What are plasticizers?
Plasticizers are generally clear, organic, liquid materials that are added to PVC formulation to obtain a flexible film to enhance both processability and serviceability of the end product. Plasticizers are very compatible with PVC resin and become an integral permanent part of the film matrix. Generally Phthalate, Adipate and Polymeric Plasticizers are used in the formulation of PVC geomembrane and are referred to as primary plasticizers because of their excellent compatibility with the PVC resin even at very high levels.
