What is the purpose of plasticizers?
PVC liner production involves mixing or blending PVC resin, stabilizers, plasticizers and pigments. The plasticizer softens the polymer to make it pliable to aid in Calendering (manufacturing) process and provide a flexible sheet which is easy to seam in both factory and field conditions by a variety of methods. When plasticizer is blended with the PVC, a portion of it forms an intimate bond with the PVC, while the remainder is captured in the polymer matrix.
