Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Natural–based PVC plasticizers increased over the last few years owing to the following advantages: 1. Increase the workability 2. Low toxicity 3. Low migration 4. Good compatibility with PVC 5. Provided from renewable and biodegradable resources 6. Increase the polymer chain flexibility 7. Reduce greenhouse gas emissions.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticization Methods & Processing with Plasticizers There are two main principal methods exist for plasticization - Internal Plasticization and External Plasticization. Internal Plasticization A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.
Ester Plasticizers for Polyvinyl Chloride - Springer
plasticizers for PVC and demonstrating the main trends in the modern progress in this eld. The studies performed can be subdivided into three groups with respect to their objectives: search for and study of new, more effective esteri cation catalysts; improvement and optimization of processes for producing plasticizers; and development of
Plasticizers Derived from Biomass Resources: A Short Review
Dynamic thermomechanical analysis (DMA) and differential scanning calorimeter (DSC) results show that these epoxidized vegetable polyol esters present excellent plasticizing effect on PVC and can be used as main plasticizers to completely replace DOP in flexible PVC films.

Developments of biobased plasticizers for compostable
Desirable plasticizer properties include good miscibility or strong intermolecular interactions between the plasticizer and the polymer resin, low volatility and diffusivity, low specific...
- Do plasticizers deteriorate the thermal stability of plasticized PVC?
- When plasticized samples were subjected to the same temperature ramp, dramatic differences were observed compared to the above results for the plasticizers alone. Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied.
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- How stable is unplasticized PVC?
- Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied. Table 3 offers a comparison of the PVC samples where the temperatures at which samples lost 10% of their initial weights have been reported.
- 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 .
- Are plasticizers able to produce Flexible PVC?
- All the ILs tested were able to produce flexible PVC. Upon 20 wt% plasticization, some of the ILs lowered the glass transition temperature ( Tg) of PVC more than that done by several traditional plasticizers. They showed good thermodynamic compatibility as well.
- Is adipate a good plasticizer?
- The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition temperature was 132.2 °C in relation to pure PVC and 7.7 °C in comparison to compounds based on DOP.
