PHARMACEUTICALLY USED PLASTICIZERS: A REVIEW - ResearchGate
The mechanism of action of plasticizers is described, in terms of plasticization theory and the chemical modifications that occur during this process, which account for the excellent performance...
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Handbook of Plasticizers - 3rd Edition
The book discusses new and historical approaches to the use of plasticizers, explaining mechanisms of plasticizers' action and their behavior in plasticized systems. It goes into detail on the use of plasticizers in a range of specific polymers, polymer blends, and other industrial products.

An overall mechanism of plasticizer action must give adequate explanations for this as well as the physical plasticization steps. The importance of step 5 cannot be stressed too strongly, since no

- What are the mechanisms of action of plasticizers?
- According to the mechanisms of action of plasticizers , both the "attractive forces to function" from lubricity theory and the "solvationdesolvation/aggregation-disaggregation" model from gel theory match the function of DEP in this AZO-loaded thermo-responsive NPs system.
- What is the interaction mechanism between plasticizer and asphalt?
- Therefore, this paper explores the interaction mechanism between plasticizer and asphalt from the viewpoint of molecular polarity and spatial configuration by using three van der Waals forces, namely dipole–dipole attraction, induction force, and London dispersion force.
- What are the theories of plasticization?
- Many such e orts were limited to certain types of plasticizers and individual MDPs -e.g., Wypych 37 Major theories for plasticization include the lubricity theory 40 , gel theory 41 , and free-volume theory 42 . These theories are all phenomenological in nature and also lack molecular details. ... ...
- How do Plasticizers improve polymer material flexibility & durability?
- Plasticizers improve polymer material flexibility and durability by lowering glass transition and cold flex temperatures. While many different classes of plasticizers have been synthesized and used...
- What theories explain external plasticizer action?
- Four general theories have been proposed to explain external plasticizer action. Some theories involve detailed analysis of polarity, solubility, and interaction pa-rameters and the thermodynamics of polymer behavior, whereas others treat plas-ticization as a simple lubrication of chains of polymer from each other.
