The tensile strength of G-plasticized films notably decreased from 9.59 to 1.67 MPa and that of S-plasticized films dropped from 28.35 to 5.84 MPa as plasticizer concentration increased from 15% to 45%. In the case of GS-plasticized films, tensile strength reduction was observed from 15.82 to 3.99 MPa at the same range of plasticizer concentration.
Plasticizers – Benefits, Trends, Health, and Environmental
The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer. The combinations are almost endless, but only a very limited number have survived the rigorous performance, cost, availability, health, and environmental requirements that are imposed by the market including by users and
Development and Characterization of Edible Film Made
The effect of plasticizer concentration on the elongation of MKS films showed reverse trend compared with their TS. Considerable increase in film elongation was noticed from 17.78 to 37.06% for G-plasticized films, 17.27–29.74% for GS-plasticized films and 4.02–35.02% for S-plasticized films with increasing concentration of plasticizers
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
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 rheologica
- Do plasticizers affect the functional properties of biodegradable gelatin-based films?
- Thus, addition of plasticizers into the film materials improves the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, and rigidity. This study aims to review the current findings on how plasticizers impact the functional properties of biodegradable gelatin-based films.
- Does plasticizer type affect tensile properties of biodegradable sugar palm starch films?
- The effect of different plasticizer type (glycerol (G), sorbitol (S) and glycerol/sorbitol (GS)) and concentration (15, 30 and 45, w/w %) on the tensile properties of biodegradable sugar palm starch films were evaluated.
- Do plasticizers affect mechanical properties?
- For food packaging applications, mechanical properties are of vital importance, so it is highly important to have general knowledge about the effect of plasticizers on mechanical properties, as well as on physical, thermal, and barrier properties, to be able to develop successful packaging materials.
- Do plasticizers soften thermomechanical properties?
- The effect of the different single-component plasticizers (glycerol, propylene carbonate and ethylene carbonate) on the mechanical and dynamic thermomechanical properties of the films were studied. Moreover, the softening effect of the two-component plasticizer based on deep eutectic solvents (DESs) was addressed.
- 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%.
- Do plasticizers affect alginate-based films?
- Some reviews on the effect of plasticizers are about improving the flexibility of the most common biopolymers such as PLA and starch [10, 11], but there is no dedicated article focusing the effect of plasticizers on alginate-based films, in particular.
