Worldwide concerns on the endocrine disruption of phthalate derivatives have sparked extensive research on its alternatives. One of the most prominent use of phthalate derivatives are on the plasticization of polyvinyl chloride (PVC). Therefore, numerous carboxyl acids and their derivates have been studied as candidates for PVC plasticizer. Elastomeric polyurethanes have been extensively studied as solid-state plasticizer to induce flexibility to otherwise rigid PVC. In this research, bio-based polyurethane (BPU) elastomers and phthalate hybrid plasticizer was used for the fabrication of flexible PVC. Even though half the amount of phthalate plasticizer was replaced with BPU the PVC with the hybrid plasticizer showed strain at break of 320.5 %. The of BPU reduced phthalate use by increasing the flexibility of PVC and reduced the migration of phthalate plasticizer.

全世界对邻苯二甲酸酯衍生物的内分泌破坏的关注引发了对其替代品的广泛研究。邻苯二甲酸酯衍生物最主要的用途之一是在聚氯乙烯（PVC）的增塑上。因此，已经研究了许多羧酸及其衍生物作为PVC增塑剂的候选物。弹性聚氨酯作为固态增塑剂已被广泛研究，以诱导对其他硬质PVC的柔韧性。在这项研究中，生物基聚氨酯（BPU）弹性体和邻苯二甲酸酯杂化增塑剂用于制造柔性PVC。即使用BPU代替了一半的邻苯二甲酸酯增塑剂，具有杂化增塑剂的PVC的断裂应变仍为320.5％。
