The Effect of Low Levels of Plasticizer on the Rheological
The low level of plasticizer in PVC increases the tensile strength and elongation at break but with an increased plasticization level of the PVC beyond the plasticization threshold. Thus,...
The effect of low levels of plasticizer on the rheological
Plasticizers play a key role in the formulation of semirigid and flexible PVC and in determining their physical properties and processability. This study examines the effects of the low phr levels of plasticizer (DOP) on the rheological and mechanical properties of rigid and semi-rigid PVC/newsprint-fiber composites.

Effects of plasticizer type and concentration on rheological
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. Based on the analysis of rheological properties of chitosan/zein film-forming
- 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.
- Does plasticizer have a low viscosity?
- And plasticizer have a low viscosity, which would increase the fluidity of biopolymer chains, leading to the softening of structure of film and the decrease of tensile strength . The TS value of C/ Z -S film was the significantly lowest (p < 0.05) than that of C/Z-P and C/Z-G film.
- Does plasticizer concentration affect viscosity of film forming solution?
- The flow index of film-forming solution increased and apparent viscosity decreased with the increase of plasticizer concentration. The storage modulus (G′) and the loss modulus (G″) decreased when plasticizer was added.
- How does plasticizer affect TS values?
- As was shown in Table 3., TS values of films reduced significantly (p < 0.05) with the increasing concentration of plasticizer. This was achieved by lowering the interaction of biopolymer chains.
