Nontoxic bio-plasticizers for PVC as replacements

In order to improve those two properties, PVC is often blended with plasticizers . Unfortunately, often there is migration of plasticizers to the surface [, , ], resulting in very soft, sticky, and fragmented PVC products. Studies have shown that plasticizers containing a benzene ring would result in low migration rates.

Plasticizers can be used alone or in combination to get the desired properties such as tensile and tear strength or low temperature flexibility. The molar mass and physical size of the plasticizer and the solubility parameters of PVC plasticizers have the major effect on the dipole attraction and thus the final properties of a flexible compound.
