Polymers | Free Full-Text | Effect of Plasticizer Type and
The type and concentration of plasticizer employed has significant effect on the physical, thermal, mechanical and barrier properties of films [ 35, 50, 51, 52 ]. The most common plasticizer utilized for starch based films are polyols such as glycerol and sorbitol, amongst many others.
Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.

Study of the effect of the addition of plasticizers on the physical
In this study, T g and T m values of the plasticized and neat kefiran films were obtained to study the effect of polyols type and concentration on these parameters. The DSC thermograms ( Fig. 3 b) shown in all cases only two transitions, one associated with the glass transition and the other with endothermic peak related to kefiran melting ( Shahabi-Ghahfarrokhi, Khodaiyan, Mousavi, & Yousefi
Effects of plasticizer type and concentration on rheological, physico
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 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.
- Do plasticizers affect the structural and physical properties of curdlan edible films?
- Conclusions This study investigated the effects of various plasticizers—glycerol (GLY), ethylene glycol (EG), propylene glycol (PRO), xylitol (XY), sorbitol (SOR), and polyethylene glycol (PEG)—on the structural and physical properties of curdlan (CL) edible films.
- Do plasticizers reduce surface hydrophobicity of Cl films?
- The addition of plasticizers reduces the surface hydrophobicity of CL films due to the hydrophilic nature of the plasticizers, which increases the film’s affinity for water. The distinct trend in the CA of PRO-containing films may result from their lower WVP compared to XY- and EG-containing films, leading to higher hydrophobicity.
- Which polymer has a plasticizing effect?
- Plasticizers were dissolved in the polymer and dispersed evenly, increasing the free volume of the polymer, separating chains from each other and facilitating chain movement [21, 30, 36, 37]. The results showed that glycerol, PEG-400 and sorbitol had obvious plasticizing effect. Fig. 2.
- 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.
- What are the mechanical properties of Cl edible films with plasticizers?
- The dynamic mechanical properties of CL edible films with various plasticizers are presented in Figure 4. The temperature corresponding to the maximum value of the tan δ peak represents the glass transition temperature (Tg). After the incorporation of plasticizers, the Tg of the films decreases, as shown in Table 3.
