Effect of plasticizer type and concentration on
Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility. On the contrary, density and water absorption of plasticized films decreased with...
The Effect of Concentration and Type of Plasticizer on the
The Effect of Concentration and Type of Plasticizer on the Mechanical Properties of Cellulose Acetate Butyrate Organic-Inorganic Hybrids 143 be used as lower cost, partial replacement for a primary plasticizer. It is possible that a plasticizer used in one formulation as a primary plasticizer could be used in a second
Effect of glycerol plasticizer loading on the physical
Mali et al. 52, analyzed the impact of glycerol with the concentration of (0–40%) on tapioca, corn, and yam starches and showed that, regardless of starch types, the tensile strength decreased
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.
Effects of plasticizer type and concentration on the
Plasticizer type and concentration showed no effects (P ≥ 0.05) on the lightness (L* value) of the film. The addition of glycerol showed no effects ( P ≥ 0.05) on the redness ( a * value) or yellowness ( b * value) of the films, while there was a slight increase in the a * and b * values when sorbitol was added as the plasticizer.
- Do plasticizers affect the performance of starch films?
- J. Tarique et al. reported that different plasticizer concentrations had an impact on the physical, structural, mechanical, thermal and barrier characteristics of plasticized films; the inclusion of plasticizers improves the performance of starch films as a whole. Similar findings were recently reported by other researchers .
- Does plasticizer concentration affect thermal properties of s-plasticized films?
- Change in plasticizer concentration showed an insignificant effect on the thermal properties of S-plasticized films. The glass transition temperature of SPS films slightly decreased as the plasticizer concentration increased from 15% to 45%.
- Does plasticizer concentration increase W/W?
- (15%–45% w/w). The results show that increasing the plasticizer concentration from 15% to 45% 8.514 × 10 −10 g·s−1·m−1·Pa−1 for GS-plasticized films. The plasticized films exhibited increased WVP values regardless of plasticizer type.
- Does increasing plasticizer concentration affect water absorption of plasticized films?
- On the contrary, density and water absorption of plasticized films decreased with increasing plasticizer concentration. Raising the plasticizer content from 15% to 45% showed less effect on the moisture content and water absorption of S-plasticized films.
- 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 concentration affect permeability of chitosan/Zein films?
- The permeability of films increased significantly with the increase of plasticizer concentration, but the C/ Z -P film (plasticized chitosan/zein film with PEG-400) had better barrier performance compared with the other two. The C/ Z -P film had better mechanical properties and light transmission.
