Green plasticizers derived from epoxidized soybean oil for poly (vinyl
In particular, the PVC sample plasticized by cardanol-based polyoxyethylene ether acetate (CPEA) with the shortest alkyl ester demonstrated 1.6-fold increase of the elongation at break along with 20.8-fold increase of migration resistance in leaching tests compared with those of PVC specimen plasticized by DOP.
Mechanical and barrier properties of polyvinyl chloride plasticized
Plasticized polyvinyl chloride (PVC) films were prepared by melt compounding and compression molding using epoxidized cardanol (EC), a biobased plasticizer and its plasticization effect was...
Plasticizers Derived from Biomass Resources: A Short Review
PVC films plasticized with epoxidized castor oil based diglycidyl ester show good elongation at break (332.9%) and remarkable increase in flexibility and plasticization than DOP. In addition, the tung-maleic triglycidyl esters, which has similar chemical structure with epoxidized castor oil based diglycidyl, is also reported [ 32 ].
Design and Synthesis of Epoxidized Soybean Oil
Compared with DOP, the ECT plasticized PVC can exhibits better thermal stability, more excellent tensile strength (17.28 MPa) and higher stretchability (629.41%), which is 1161% higher than DOP (1
Research progress of novel bio-based plasticizers and their
The synthesis route of epoxidized castor oil-based ester is shown in Scheme 1. They added these prepared plasticizers to PVC as the main plasticizer and compared their plasticizing properties with epoxidized soybean oil (ESO) and dioctyl terephthalate (DOTP).
- What are bio-based plasticisers for polyvinyl chloride (PVC)?
- Novel bio-based plasticisers for polyvinyl chloride (PVC) are a significant and growing area of interest. These compounds aim to replace toxic and petro- chemical additives in commonly used plastic products. Plasticisers can com- prise as much as 50% of the total mass of the PVC product. Epoxidised soybean
- Can epoxidized soybean oil be reprocessed?
- Vegetable oils such as epoxidized soybean oil (ESO) are not recyclable and cannot be reprocessed due to the cross-links in their structure (Liu et al. 2020b) ESO is preferred as a plasticizer and stabilizer for polyvinyl chloride additives (He et al. 2020).
- Are bio-based plasticisers suitable for PVC compounding?
- epoxide groups per molecule). These products were evaluated as potential bio-based plasticisers for PVC compounding, with the aim of matching the performance of the petrochemical plasti- cizer DOP. mPEG-ESBO showed the greatest plasticising behavior as measured by Tg suppression and tensile prop- erties.
- What is epoxidised soybean oil (ESBO)?
- Epoxidised soybean oil (ESBO) is a commercially available bio-based plasticizer that is typically used at lower levels than traditional phthalates in PVC compounds because it does not show equivalent performance to existing phthalate plasticisers. Four derivatives of ESBO have been synthesized through reaction at the epoxide rings.
- What is the strain behavior of commercial PVC plasticisers?
- strain behavior to the commercial PVC plasticisers. These samples displayed ductile behavior prior to break, with no necking of the sample, followed by a brittle fracture as indicated by SEM images (supplemental data).
- Which plasticizer has the lowest TG?
- IEEP showed the lowest average Tg, but the peak width was more than double that of ESBO (FWHM of 82.2 C compared with 39.7 C). The peak width of mPEG-ESBO 10 was also broad, despite this plasticizer generally showing good performance in other material properties.
