Thesis | Rheology of 'green' plasticizers: application
The viscoelastic master curves of the elastic and viscous moduli, G' and G", respectively, for the ‘green’ plasticizers compared favourably to those of the commercial plasticizers, and therefore it was concluded that the ‘green’ plasticizers exhibited similar rheological behaviour to the commercial plasticizers, as seen by the

Processes 2017, 5, 43 2 of 13 87% of the global plasticizer market [3]. The most prevalent phthalate plasticizer is di(2-ethylhexyl) phthalate (DEHP) [4]. Most plasticizers are incorporated into
Rheology of ‘Green’ Plasticizers: Application of Time
My thesis research aimed to document the 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.
- 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.
- 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].
- 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 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 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.
- Does polymer molecular weight affect rheological properties of Green Sheet?
- Experiments were performed to elucidate the effects of the polymer molecular weight and its end-to-end distance on the properties of green sheet as well as on the rheological properties of casting slips. Tapes (thickness=200 μm) were cast from these slips and their properties were evaluated.
