Plasticizers: Types, Uses, Classification, Selection & Regulation
When added to polymer, these plasticizers provide several benefits as listed below. They make a product softer, improve flexibility The processing becomes possible or easier Plasticized products do not break easily at cold temperatures Plasticization Methods & Processing with Plasticizers
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.
The effect of plasticizers on the functional properties
The polarity of plasticizer molecules may also influence the effectiveness of the plasticizer. Polar plasticizers must be used with polymers containing polar groups to achieve good compatibility. There is a higher chance for plasticizer polarity to overcome the forces between the polymer molecules as the distance between the polar groups along the polymer chain gets smaller.

The use of starch based films as a potential alternative choice to petroleum derived plastics is imperative for environmental waste management. This study presents a new biopolymer (sugar palm starch) for the preparation of biodegradable packaging films using a solution casting technique. The effect of different plasticizer types (glycerol (G), sorbitol (S) and glycerol-sorbitol (GS
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.
- 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.
- Does plasticizer type affect optical properties of bioactive edible films?
- The effects of plasticizers type and concentration on the optical properties of bioactive edible films were shown in Table 3. The result indicated plasticizer improved the opacity of chitosan/zein blend films, and the opacity of films was increased significantly (p < 0.05) with an increase of plasticizer concentration.
- Do plasticizers reduce opacity?
- The effect of various plasticizers shows different results; the addition of fructose tends to reduce the opacity at 25% and 35%, with 0.620 and 0.6246 nm/mm, respectively, which was the lowest opacity for all samples. Plasticizing films with fructose, glycerol and sorbitol with 15% load showed an opacity higher than 25% and 35% of the plasticizer.
- What are the benefits of plasticizers?
- In addition, the softening effect of plasticizers can improve the flow properties of the blend, with reduced viscosity and better dispersion of fillers in the matrix .
- 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.
- How does the type of plasticizer affect biopolymer properties?
- The type of plasticizer can strongly affect the barrier properties, water uptake, and mechanical properties of the biopolymer.
