Special Issue "Green Plasticizers for Polymers" - MDPI
The scope of this issue ranges from synthesis of green plasticizers, enhancement of physical and rheological properties, migration of plasticizers upon disposal, relationships between plasticizers and human health, and life-cycle-assessment. Particular emphasis will be placed on the design and evaluation of new green plasticizers, using the
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer widely used in large applications due to the excellent balance between cost and properties. Due to the environmental and human health concerns of consumption of petrochemical-based plasticizers, the use of bio-based plasticizers has been increasing. The new blends of PVC made with green
A potentially general approach to aliphatic ester-derived PVC
This approach harnesses the α-proton, a structural feature shared by all aliphatic esters, and dialkyl carbonate, an established “green chemical”, thus providing a potentially general and green route towards DEHP alternatives with unprecedented performance that may contribute to sustainability of the old and oft-maligned PVC industry.
Poly(-caprolactone)-based ‘green’ plasticizers for poly
The ideal ‘green’ plasticizer for PVC should display the following properties: (1) facile biodegradation; (2) non-toxicity of both the plasticizer and the possible metabolites; (3) miscibility with PVC; (4) plasticization efficiency comparable to DEHP; (5) good processability and high performance in PVC products; (6) high resistance to
Title: A Review on Plasticizers and Eco-Friendly
Various efforts for producing more eco-friendly plasticizers have been carried out by using biobased sources such as diester succinates, which display better biodegradation behavior and...
- Is PVC a “green” plasticizer?
- However, reduced leachability from PVC is the most desirable criterion of a “green” plasticizer for one important reason: the problems of high plasticizer toxicity, slow biodegradation and reduced mechanical properties due to plasticizer loss are all contingent on the plasticizer leaving the polymer matrix.
- Can esters provide a green alternative to toxic phthalate plasticizers?
- The ester mixture that was found to be the most favorable plasticizer was characterized by good thermal and thermo-oxidative stability (5% weight loss temperature: 227.8 °C in air and 261.1 °C in nitrogen). The results of the research clearly indicate that the synthesized esters can provide a green alternative to toxic phthalate plasticizers. 1.
- Are plasticizers environmentally friendly?
- Four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed by gas chromatography (GC) and infrared spectroscopy (FT–IR) analyses, and their physicochemical properties and thermal stability (TGA analysis) were investigated.
- Why are plasticizers replaced with a compatible & non-toxic ester plasticizer?
- To avoid the negative effects caused by plasticizer migration and at the same time maintain the good properties of soft PVC, low-molecular-weight plasticizers were replaced with compatible and non-toxic ester plasticizers.
- Which PVC plasticizer is best for biodegradation?
- DHS was found to be the best PVC plasticizer, which is a compromise between longer molecules favorable for plasticization and shorter molecules favorable for biodegradation.
- Can plasticizers replace petroleum-based plasticizer in PVC applications?
- Compared to DINP and DEHP, the migration was as much as 70% lower for each plasticizer concentration. Thus, due to their good compatibility, efficiency and thermal properties, the plasticizers synthesized in this research have the potential to replace petroleum-based plasticizers in PVC applications.
