  • Which plasticizer has a good plasticizing efficiency?
  • Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
  • Which plasticizer is used for outdoor cables and aerospace parts?
  • Bis (2-ethylhexyl) sebacate (DOS) and bis (2-ethylhexyl) azelate (DOZ) are the two plasticizers most used for the application mentioned, especially for outdoor cables and aerospace parts. Resistance to extraction is a very important performance characteristic in plasticized materials.
  • 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.
  • Can plasticizers reduce material degradation over time?
  • The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
  • What makes a polymer a good plasticizer?
  • It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
