Rheology of Green Plasticizer/Poly(vinyl chloride
In this work, the time-temperature profiles of PVC blended with our replacement green plasticizers-succinates, maleates, and dibenzoates, of varying alkyl chain length-are compared to blends...
Tailoring and Long-Term Preservation of the Properties of PLA
Due to the strong plasticizing effects of TBC (even at 10%), the plasticized composites are characterized by significant decrease of T g and rigidity, increase of ductility and impact resistance. Correlated with the amounts of plasticizer, a dramatic drop in melt viscosity is also revealed.
Designing Green Plasticizers: Linear Alkyl Diol Dibenzoate
The discussed diol dibenzoate compounds showed good plasticizing effectiveness in PVC, andcoupled with the low toxicity profiles of the compounds in bacteria (except 1,3-PrDB) , mammalian cell in-vitro assays [26,27], and an in-vivo study of 1,4-BDB with a focus on reproductive toxicity [28,29], these compounds appear to be good green
[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.
- How does plasticizer affect the rheological properties of film-forming solution?
- Plasticizer influenced the rheological properties of film-forming solution. Plasticizer was efficient for the improvement of properties of blend film. The chitosan/zein film with PEG-400 exhibited superior properties.
- 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.
- 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 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 type affect chitosan/Zein film rheological and structural properties?
- The chitosan/zein film with PEG-400 exhibited superior properties. The purpose of this study was to evaluate the effect of plasticizer type (glycerol, PEG-400, and sorbitol) and concentration (0%, 15%, 30% and 45%, w /w dry polymer weight) on rheological and physico-mechanical and structural properties of chitosan/zein blend film.
