While the glass transition temperatures showed an insignificant effect with high plasticizer content. Regardless of plasticizer sort, the tensile stress and Young’s modulus of plasticized films decreased as the plasticizer concentrations were raised beyond 25%. Likewise, the relative crystallinity decreased by increasing the plasticizer
Influence of plasticizer content on the transition of electromechanical
The influence of plasticizer (dibutyl adipate) content on electromechanical behavior of PVC gels was investigated by impedance spectroscopy and space charge measurement.

Influence of plasticizer content on the transition of electromechanical
The influence of plasticizer (dibutyl adipate) content on electromechanical behavior of PVC gels was investigated by impedance spectroscopy and space charge measurement. By plasticizing the PVC, the dielectric constant and space charge density of PVC gel were drastically increased at 1:2 w/w ratio of PVC to plasticizer.
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.
Effect of Plasticizer Content on the Structure and
The influence of plasticizer content on the structure and properties of the blends was explored by observing the microstructure, mechanical and thermal properties of the blends. The results showed that with the increase of glycerol content, the crystallization temperature and melting temperature of the blend system increased, the chain segment was easier to move, and the glass transition
- Do plasticizers affect structural transitions and heterogeneity of poly(vinyl alcohol) films?
- Effects of Plasticizers on Structural Transitions and Heterogeneity of Poly (vinyl alcohol) Films as Studied via AIE Materials Solution casting is a common processing method in industrial production. The phase-structure transitions driven by solvent evaporation directly impact the quality of the final film.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- Are plasticizers prone to migration?
- However, when incorporated in the polymer matrix, plasticizers are prone to migration. CA products can suffer embrittlement, cracking, warping, or discoloration during their life cycle, affecting the material’s integrity and durability.
- Why does the plasticizing efficiency of different substituents vary?
- Anyway, the plasticizing efficiency of different substituents can vary because of their structural features, and it is strictly correlated to the molecules’ mobility within the polymer matrix.
- Why does plasticization occur?
- Indeed, plasticization occurs because of the ability of plasticizer molecules to create secondary bonds with polymer and to replace chain interactions by plasticizer-polymer bonds . Based on these considerations, plasticizers with low molecular weight and a few polar groups provide higher flexibility and plasticization.
- Does oil-type plasticizer improve freezing resistance?
- Moreover, there was a remarkable decrease of Tg using DOA plasticizer, which shows more effective on freezing resistance. However, there was not much change in Tg with oil-type plasticizers with high oil content compared to TCP plasticizer.
