Therefore, in this work, the rheological behavior of PVC blends prepared with the three families of green plasticizers ( Figure 1) was compared to that of blends containing DEHP and DINCH to gain a better understanding of the blends’ dynamic rheological behavior under processing conditions.
Rheology of ‘Green’ Plasticizers: Application of Time
rheological behaviour of PVC plasticized with our ‘green’ plasticizers and compare the results to the rheological behaviour of PVC plasticized with commercially available plasticizers including DEHP. The rheological behaviour was characterized using dynamic mechanical analysis and discrete relaxation time spectra.

Tailoring and Long-Term Preservation of the Properties of PLA
TBC is one of the most effective plasticizers for PLA, produced using entirely renewable components (i.e., citric acid and n-butanol, as raw materials). Former studies showed that between 10 and 20 wt.% of plasticizer in PLA, results in a higher elongation at break and lower T g compared to the unplasticized PLA [ 40 ].
- Does plasticizer type affect rheological behavior and solid loading?
- Conclusion The type and content of plasticizer had substantial effects on the rheological behavior and solid loading, leading to differences in macro / micro structure and property of the green body and sintered part. The shear shinning and thixotropy behaviors were characterized for both PEG-400 and DBP cases.
- How do plasticizers affect rheological behavior and solid loading of ceramic paste?
- The type and content of plasticizers (polyethylene glycol (PEG) and dibutyl phthalate (DBP)) had substantial effects on the rheological behavior and solid loading of ceramic paste, leading to varied macro / micro structure and strength of the green and sintered parts.
- Should plasticizer be used in stereolithography-based additive manufacturing?
- Adding plasticizer is an efficient way to regulate the rheological behavior of ceramic paste and quality of green body in stereolithography-based additive manufacturing.
- Does plasticizer improve the toughness of green bodies?
- The dimensions of feature part are larger than those of the test samples, and the structure is more complex and no chamfering at right angles, which can more clearly reflect the effect of the plasticizer in improving the toughness of the green bodies and reducing the damage caused by the inner stress and shrinkage [14, 32].
- How do plasticizers work in ceramic manufacturing?
- Generally, plasticizers have three functions in ceramic manufacturing. Firstly, the plasticizer molecules intercalate between the polymers by increasing the spacing between the polymers and reducing the van der Waals forces and friction between the molecules, thereby achieving low viscosity .
- How does plasticizer content affect flexural strength?
- In the case of the same plasticizer, the concentration of monomer decreases as the plasticizer content increases, which means the decrease of the flexural strength of the green body with increasing plasticizer content. This trend can be observed in the DBP group.
