However, the long-term rheological performance is a key requirement for many materials used in seals, gaskets, etc., and must be evaluated as part of the process to assess the viability of green plasticizers as phthalate replacements.
[PDF] Rheology of Green Plasticizer/Poly(vinyl chloride
Our group has developed several replacement compounds that have good biodegradation kinetics, low toxicity profiles, and comparable plasticizer properties to DEHP. Knowledge of the rheology of PVC–plasticizer blends at elevated temperatures is crucial for understanding and predicting the behavior of the compounds during processing.
Designing Green Plasticizers: Linear Alkyl Diol Dibenzoate
However, upon heating to temperatures above 60 °C, effective plasticization was again observed. 1,4-Butanediol dibenzoate is thereby a reversible heat-activated plasticizer or processing aid with...
Rheology of ‘Green’ Plasticizers: Application of Time
endocrine disruptor in humans. As such, there has been an effort to synthesize new ‘green’ plasticizers, with more favorable biodegradation behaviour. It is important to ensure that these ‘green’ plasticizers have comparable mechanical properties to their commercial counterparts. My thesis research aimed to document the
- 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.
- 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.
- 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.
- What are plasticizers used for?
- Plasticizers are added to hard and brittle polymers such as poly (vinyl chloride) (PVC), resulting in lower melt viscosity, lower glass transition temperature (Tg), lower elastic modulus, and better elongation of the blend, or any combination of these properties .
