Research progress of novel bio-based plasticizers and their
We have reviewed recent research progress on different types of novel bio-based PVC plasticizers and assorted them by raw materials and chemical structure. Through in-depth analysis of the relationship between the chemical structure and the plasticizing performance, the efficiency of plasticizers may be predicted before they have been designed.
Synthesis and properties of a bio-based PVC plasticizer
A novel green plasticizer, acetylated lactic acid 1,6-hexane diester (ALHD), was successfully synthesized based on L-lactic acid, a renewable organic acid from corn starch. Its chemical structure was characterized using FTIR, 1H NMR and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).
Recent Developments of Biobased Plasticizers and Their Effect
Growing awareness of the effects of plasticizers on the environment and the depletion of petroleum-based resources has made the development of an alternative biobased plasticizer for PVC formulation necessary.
Developments of biobased plasticizers for compostable
Moreover, the effect of biobased plasticizer concentration, interaction, and compatibility on the polymer properties has been examined. Recent developments have resulted in the replacement of synthetic plasticizers by biobased counterparts. Particularly, this has been the case for some biodegradable thermoplastics-based packaging applications.
- Are cardanol- and isosorbide-based plasticizers a promising material?
- Among a variety of newly developed biobased monomers, cardanol, and isosorbide are the two most promising materials because of their unique structural features. This review summarizes the research progress of cardanol- and isosorbide-based plasticizers with synergistic effects of plasticization, thermal stabilization, and anti-migration.
- Which biobased precursors are used to make plasticizers?
- A great variety of other biobased precursors have been used for the generation of plasticizers . Prominently among these have been cardanol [19 – 21] (a byproduct of cashew nut processing), tartaric acid [22 – 25] (a byproduct of winemaking) and derivatives of starch, isosorbide [26, 27] and the furanics [28 – 32].
- Are plasticizers made from biomaterials?
- Some, including those prepared from plant oils, have been generated from biomaterials themselves. However, the more numerous and generally more effective have been generated from discrete compounds produced from various biomaterials. Several structural features of effective plasticizers have been recognized.
- 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.
- Can bio-based plasticizers be made from biomass?
- Broadly speaking, there may be more suitable biomass renewable raw materials that can be used to prepare bio-based plasticizers, which still need to be explored and discovered by researchers in the future.
- What is the relationship between plasticization structure and plasticization efficiency?
- Based on the explanation of plasticization mechanism, the relationship between plasticizer structure and plasticization efficiency can be further explored. Generally speaking, plasticizers with small molecular weight have higher plasticization efficiency .
