Plasticizers work by spacing out polymer molecules, lowering the glass transition temperature and enhancing flexibility. The most widely used plasticizers are phthalates, which account for over 90% of plasticizer use and are primarily used in PVC. Over 6 million tons of plasticizers are produced annually, with 80-90% used in PVC for applications like flooring, cables and medical devices. Plasticizers increase
