plasticizer migration

Bio

Plasticizer migration was not observed in proportion to the amount the plasticizer replaced (65 wt %) The benzyl ester plasticizer obtained in this study showed good incorporation and plasticizing performance into the PVC polymer matrixes thus making the castor oil based plasticizer an environment friendly substitute for the PVC systems
