The tensile strength of plasticized HPMC films was generally lower than that of control HPMC film and could be attributed to increased crystallinity and segmental chain mobility of HPMC. This effect increased as the concentration of plasticizer increased.

The plasticizers were mineral oil-based products with a varying amount of the aromatic bound carbon C/A. With increasing C/A, the resistance against initiation and propagation of a slow, stable crack changed and also the resistance against unstable crack propagation was influenced.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). 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
- Do all plasticizers have a plasticizing effect?
- Though all these plasticizers showed plasticizing effect, their plasticizing efficiency are different.
- 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.
- How does plasticizer affect the crystallinity of polymer films?
- In the presence of plasticizer, the characteristic peaks of HPMC and HPS were greatly intensified as expected, since the small molecules induces polymer chains to move readily and provides more chances for collision and interaction of the macromolecules, leading to an increase in the crystallinity of the films.
- 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.
- Do plasticizers affect hydroxypropyl methylcellulose / hydroxy propyl starch blends?
- In this study the influences of plasticizers on the structures and properties of hydroxypropyl methylcellulose/hydroxypropyl starch blends were investigated. The self-similar structure was significantly affected by the type of plasticizers.
