  • How can plasticizer migration be inhibited?
  • Therefore, migration of plasticizer can be inhibited by the three following ways: (1) using plasticizers with higher molecular weight and hyperbranched degree, (2) increasing the interaction between plasticizer and PVC matrix, (3) modifying or coating the surface of soft PVC by physical or chemical methods for restricting the plasticizer migration.
  • What is the mechanism of action of plasticizers?
  • The mechanism of the action of plasticizers is described, in terms of plasticization theory and the chemical modifications that occur during this process, which accounts for the excellent performance of some plasticizer molecules and the apparently poor softening ability of others.
  • What are the three stages of plasticizer migration?
  • There are three stages for the migration of plasticizer: (1) the plasticizer diffusion from the inside to the surface, (2) the plasticizer through the surface, (3) the plasticizer through the surface to the external medium .
  • How can plasticizers be used in industrial applications?
  • External plasticization using low molecular weight plasticizers is the most widely applied approach in industrial applications. The glass transition temperatures and the mechanical properties (elastic modulus) of CA systems with different plasticizer contents are reported in Table 2.
  • How does a plasticizer interact with a polymer?
  • In CA, plasticizer-polymer interactions begin with the mixing step: the plasticizer first wets the polymer particles and then diffuses and solvates the amorphous domains of the polymer thanks to externally added heat (e.g., heating jacket on the mixer) or heat generated internally by the friction between macromolecules.
  • What is a plasticizer & how does it work?
  • A plasticizer is a substance the addition of which to another material makes that material softer and more flexible. Most often plasticizers are materials that, when added to a polymer, cause an increase in the flexibility and workability, brought about by a decrease in the glass-transition temperature, Tg, of the polymer.
