Title: A Review on Plasticizers and Eco-Friendly
Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility. These properties are a result of the association of...
Plasticizers – Benefits, Trends, Health, and Environmental
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.
Effects of plasticizer type and concentration on rheological
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. Based on the analysis of rheologica
Plasticizer - an overview | ScienceDirect Topics
Plasticizers may comprise 15–50% of a PVC formulation. By changing type and amount of plasticizer, properties can be tailored to requirements. Increasing plasticizer concentration increases flexibility, decreases tensile strength, and reduces hardness (e.g., Figure 1 ).

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
- Do plasticizers affect the functional properties of biodegradable gelatin-based films?
- Thus, addition of plasticizers into the film materials improves the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, and rigidity. This study aims to review the current findings on how plasticizers impact the functional properties of biodegradable gelatin-based films.
- Are polyols a good plasticizer?
- Polyols are good plasticizers for protein-based materials such as gelatin films. Beneficial compounds of plasticized gelatin film can be used as biodegradable food packaging. Glycerol and sorbitol were found to show considerable plasticizing effect on gelatin-based film.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Can -lactoglobulin films be plasticized with different plasticizers?
- The addition of combined plasticizers (GLY and PEG) can modify the mechanical properties and water vapor permeability . β-Lactoglobulin films were plasticized with different plasticizers (PG, GLY, sorbitol, PEG 200, PEG 400 and sucrose) aiming at improving the mechanical properties.
- What is low-molecular-weight plasticizer?
- Low-molecular-weight plasticizer is one of the major additives used in PVC compounding. The addition of plasticizers to a PVC formulation decreases many mechanical properties of the PVC product (hardness, tensile strength, modulus, etc.); however, low-temperature flexibility, elongation, and the ease of processing are all improved.
- Do polyols affect mechanical and surface properties of chitosan films?
- The effect of polyols such as GLY, EG, PEG and PG on mechanical and surface properties of chitosan films was evaluated considering the plasticizer volatility , since it may influence film properties and stability during application and storage, i.e. the less volatile the plasticizer, the better it is for use.
