Polymers | Free Full-Text | Effect of Various Plasticizers
Plasticizers were added to improve the flexibility and homogeneity of the wheat starch-based bioplastic. Control film exhibited high tensile strength (38.7 MPa) with low elongation (1.9%). However, films plasticized with 35% sorbitol showed the highest elongation, which was 60.7% at break.
Effect of Plasticizer Percentage on Thermal Properties
The results showed that the thermal stability of plasticised PVC was improved by increasing DOP percentage, but in the same time has a reverse behavior where the LOI decreases as the DOP...
Effect of plasticizers on physical, thermal, and tensile
The effects of plasticizer types and contents on the physical, mechanical, morphological, as well as thermal properties of Dioscorea hispida starch films have been studied. Dioscorea hispida starch films without plasticizers were brittly accompanied by numerous visible cracks and were difficult to be peeled off the surface layer.
Effects of plasticizers on thermal properties and heat
The concentration of plasticizer was chosen based on our preliminary experiment, i.e., minimum concentration of 30% is required before the film can be sealed. The ratio of plasticizers chosen covers the combination of plasticizers from 0 to 100 percent by equal 25% interval.
Effect of glycerol plasticizer loading on the physical
Materials. Native arrowroot starch was extracted from arrowroot tubers purchased from Norient Jaya Sdn Bhd Kuala Lumpur, Malaysia. The glycerol plasticizer (with 99.5% purity) was supplied by
- 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%.
- Which plasticizer has higher thermal properties?
- In a general manner, the higher plasticizing effect on thermal properties was observed with the DTG, followed by PPG, GLY and ETG, principally with low plasticizer content. However, also in terms of thermal properties, the ETG presented the higher plasticizer efficiency followed by the GLY, DTG and PPG.
- Does plasticizer type and concentration affect biodegradable films?
- Generally, the current study verified that plasticizer type and concentration affects the mechanical, thermal and barrier properties of plasticized SPS films. In summary, this paper presents a potential biopolymer for the development of biodegradable films.
- Does plasticizer affect tensile strength of SPS films?
- The effect of different plasticizer types and concentrations on the tensile strength of SPS films is shown in Figure 1. The presence of plasticizer at lower concentration of 15% demonstrated high tensile strength value of 28.35 MPa for S-plasticized films, 15.82 MPa for GS-plasticized films and 9.59 MPa for G-plasticized films.
- Do plasticizer concentrations affect T G values of SPS films?
- Subsequently, the polymer matrix becomes less dense and the mobility of polymer chains increases [83, 84]. However, in the present study, the decrease of T g values of SPS films are insignificant as plasticizer concentrations increased from 15% to 45%. G-plasticized films demonstrated greater T g reduction when compared to S-plasticized films.
- Do plasticizers affect tensile strength?
- The different plasticizers utilized in the film-forming solution have remarkable effects on the tensile, thermal and barrier properties of the resulting films. In all the plasticized SPS films, the tensile strength decreased with plasticizer content from 15%–45%.
