  • What is plasticizer efficiency?
  • Plasticizer efficiency denotes a plasticizer's capacity to impart softness to the product. It is quantified as a ratio of the slope in the hardness-versus-plasticizer-concentration relationship. This correlation expressed in phr (parts per hundred resin), is depicted in Figure 4. Several types of plasticizers mentioned in the graph include:
  • What is plasticizer-polymer ratio?
  • The plasticizer-polymer ratio in a plasticized product is expressed in parts of plasticizer per hundred parts of polymer (PHR). For example, 50 PHR of plasticizer refers to that per 100 g of polymer; 50 g of plasticizer were added to the mixture.
  • Why does plasticizer efficiency increase in PVC?
  • In a specific group of esters sharing a common acid group, the plasticizer efficiency rises when the molecular weight of the plasticizer decreases in PVC. Additionally, enhanced plasticizer efficiency is observed with a more linear alcohol chain. Incorporating a plasticizer into a PVC product extends the lower limit of its useful temperature range.
  • What factors determine the success of plasticized systems?
  • In this scenario, fundamental parameters such as solubility, compatibility, polarity, molecular weight, and functional groups of plasticizers play a crucial role in determining the success of plasticized systems while mitigating the drawbacks of the external plasticization .
  • 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.
  • 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).
