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 WHICH IMPROVE COMPATIBILITY IN PVC
We have found that DOCH shows increased compatibility in PVC formulations where 1) high plasticizer loadings (100 phr and higher) are employed to achieve very soft PVC parts; 2) where lower cost secondary plasticizers are employed to replace some portion of the primary plasticizer and 3) where rheology is controlled by the use of viscosity
Combining Renewable Eleostearic Acid and Eugenol
The recent studies on sustainable plasticizer mainly focus on raw material source, synthesis method and plasticization, but the effect of chemical functional groups (epoxy group and ester group) of sustainable plasticizer on compatibility and thermal stability of plasticized polyvinyl chlorid (PVC) materials has been ignored. In this study, two kinds of sustainable plasticizers (eleostearic
US Patent for PVC plasticizers and methods for making thereof
Several classes of bio-plasticizers have been developed, like sebacates, citrates, succinates, isosorbides, and plasticizers derived from castor oil, epoxidized soybean oil, etc. These bio-plasticizers are esters and generally do not offer optimal PVC compatibility and/or can exhibit unfavorable leakage-by-diffusion properties.
Recent Attempts in the Design of Efficient PVC Plasticizers
Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer performance in comparison to PVC
- Are plasticizers compatible with PVC?
- By analyzing the relationship between molecular structure and performance of plasticizers, researchers found that the presence of carbon–carbon double bonds and hydroxyl groups reduces the compatibility of plasticizers with PVC, while the epoxy groups and ester bonds can improve the plasticizing capability of plasticizers on PVC.
- Why is plasticizer better than PVC?
- On the other hand, the polar groups on the plasticizer molecule, such as ester groups, will have hydrogen bonds with the hydrogen atoms on the PVC chain, making the plasticizer has better compatibility with PVC and resistance to migration. The synergy of these two aspects makes PVC materials have superior mechanical and thermal properties.
- Which plasticizer has the best plasticizing effect on PVC and PLA films?
- According to the above Tg results of plasticized PVC and PLA films, the AcMAE-C6 plasticizer exhibited the best plasticizing effect on PLA films as well as PVC films, and this phenomenon seems to be due to the structure of AcMAE-C6 having the best compatibility with both PVC and PLA.
- Is tag a suitable plasticizer for PVC?
- TAG has been used as a secondary plasticizer for PVC as a substitute or complement for traditional secondary plasticizers. The mechanical and thermal properties of the PVC formulations produced using TAG as plasticizer have been evaluated. The results suggested that TAG is a suitable plasticizer for PVC.
- Does a mixture of Plasticizers improve the mechanical properties of PVC?
- Moreover, the mechanical properties were improved when a mixture of plasticizers was applied in PVC blends, whereas a blend with pure SOHE showed worse mechanical properties (lower elongation at break and higher tensile strength) than DOP.
- Can glycerol derivative plasticizers be used for polyvinyl chloride (PVC)?
- The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives. In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC.
