Abstract
Plasticized, unpigmented and pigmented PVC films are described which utilize a biobased, phthalate ester alternative primary plasticizer. The films show comparable color performance to the phthalate ester-plasticized unpigmented or pigmented PVC films, even where the neat biobased plasticizer has a much higher Pt—Co color as measured according to DIN-6271 (ASTM D 1209) compared to the neat phthalate ester plasticizer. Biobased primary plasticizers in the form of diesters of furan-2,5-dicarboxylic acid are especially contemplated, and provide increased thermal stability to the PVC films as an added benefit.
