Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
- What determines the rate of migration between plasticizer and PVC?
- The rate of migration depends not only on the plasticizer but also on the nature of the contact material. Plasticizer can also be extracted from PVC by a range of solvents, including water. The aggressiveness of a particular solvent depends on its molecular size and its compatibility with both the plasticizer and PVC.
- How do plasticizer polar groups interact with PVC resin?
- Plasticizer is mixed with PVC resin—adsorption step. Plasticizer penetrates and swells the resin particles—adhesion step. Polar groups in the PVC resin are freed from each other—absorption step. Plasticizer polar groups interact with the polar groups on the resin— intermolecular plasticizing step.
- What percentage of plasticizer demand is DOP?
- DOP represents 50% of world plasticizer demand Source BASF estimates Petrochemicals – Industrial Petrochemicals N-CPN/I The Heart of Your Products
- What percentage of plasticizer is used by the PVC industry?
- Over 90% of the plasticizer volume is used by the PVC industry. The reason for such high usage with PVC is that the benefits imparted by the plasticization of PVC are far greater than those imparted to other polymers. PVC is the only polymer able to accept and retain large concentrations of plasticizer.
- Why do plasticizers increase the free volume of a resin?
- Plasticizers increase the free volume of the resin and ensure that free volume is maintained as the resin–plasticizer mixture is cooled from the melt, preventing interactions between neighboring polymer chains. For the plasticized resins, free volume can arise from motion of the chain ends, side chains, or the main chain.
- Why does a plasticizer impart a greater free volume per volume?
- The introduction of a plasticizer, which is a molecule of lower molecular weight than that of the resin, has the ability to impart a greater free volume per volume of material because there is an increase in the proportion of end groups and the plasticizer has a glass-transition temperature (Tg) lower than that of the resin itself.
