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...
Research progress of novel bio-based plasticizers and their
Biomass renewable resources have wide range of sources and low prices, and the chemicals obtained from them have various structures, which can provide a huge platform to design novel PVC plasticizers with the aim of replacing traditional phthalate plasticizers.
Natural-based plasticizers and biopolymer films: A review
The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
Developments of biobased plasticizers for compostable
The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been broadly investigated. The synthesis of...

The plasticizer content is another important parameter. The interactions between the plasticizer and starch are weak for a plasticizer amount below 10% wt. The material is then fragile and it is difficult to work with it. When the plasticizer content becomes higher than 20% wt, flexibility and elongation properties improved .
- What is the mechanism of plasticizing polymers?
- At present, there is no definite conclusion on the mechanism of plasticizing polymers, and researchers mostly speculate on it through experiments. Up to now, the widely spread plasticizer mechanism are the following points. The first is the free volume theory.
- Are plasticizers biodegradable?
- Plasticizers are additives used to ensure flexibility to polymer blends and thereby to increase their processability. As the typical plastic component phthalates and other fossil-based components contribute environmental issues since such compounds are not biodegradable.
- Which plasticizer is used to improve the mechanical properties of PLA?
- (32,34,37)Specifically, to improve the mechanical properties of the PLA, TEC, a nontoxic, eco-friendly, and natural plasticizer, has been widely used. (37−42) In recent years, natural cellulosic fibers have been combined with polymers for the production of low-cost and high-performance materials.
- Which plasticizer has a strong migration resistance?
- Hyperbranched plasticizer has strong migration resistance due to its unique structure. Lactic acid-based plasticizers are a very cutting-edge direction that requires more research and development. These bio-based plasticizers can give PVC materials excellent thermal and mechanical properties under the premise of resistance to migration.
- How do plasticizers affect the physical properties of a polymer?
- Additionally, the incorporation of plasticizers into the polymer can affect some physical properties of the polymer such as the viscosity, degree of crystallinity, glass transition temperature (T g ), hardness, and density [15,35]. ... ...
- Can plasticizers affect the thermal stability of PVC?
- Howell et al. synthesized four esters/ethers derived from tartaric acid. The thermogravimetric test showed that the mixing of plasticizers will not negatively affect the thermal stability of PVC. Starting from the renewable green chemical levulinic acid, Sinisi et al. synthesized five asymmetric ketal-diester plasticizers.
