Processes | Free Full-Text | Rheology of Green Plasticizer
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.
Special Issue "Green Plasticizers for Polymers" - MDPI
The scope of this issue ranges from synthesis of green plasticizers, enhancement of physical and rheological properties, migration of plasticizers upon disposal, relationships between plasticizers and human health, and life-cycle-assessment.
Rheology of Green Plasticizer/Poly(vinyl chloride
These experiments help to show that the green plasticizers described herein are viable replacements for DEHP, providing a less toxic alternative with comparable processing and rheological...

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
- 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.
- 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.
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
- What is the range of plasticizer concentration?
- The range of plasticizer concentration was determined by preliminary experiments. Glycerol (G), PEG-400 (P) or sorbitol (S) was added at different concentrations (0%, 15%, 30% and 45%, w /w, based on the weight of chitosan and zein) by magnetic stirring for 30 min, cooled to room temperature for testing.
- Which plasticizers are used in bio-films?
- Glycerol, PEG-400 and sorbitol are often used as plasticizers owing to their good compatibility and water solubility , which makes bio-films overcome brittleness and be equipped with the desirable stretchability and flexibility. The specific improvement effect was determined by the interaction between plasticizer and polymer.
- Does glycerol have a plasticizing effect?
- The results showed that glycerol, PEG-400 and sorbitol had obvious plasticizing effect. Fig. 2. Frequency sweep data for film-forming solutions with different plasticizers. (a) elastic modulus G′ versus frequency. (b) viscous modulus G″ versus frequency. (c) loss tangent tan δ versus frequency.
