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
Synthesis and properties of castor oil based plasticizers
Plasticizers prepared from vegetable oils mainly include epoxy vegetable oils, 5–8 and epoxidized fatty acid esters. 9 In these types of plasticizers, the presence of the epoxy group makes the plasticizers have a better plasticizing effect on PVC and plays a role as stabilizer. 10 When heated, PVC undergoes autocatalytic dehydrochlorination
Plasticizers Derived from Biomass Resources: A Short Review
Among numerous bio based plasticizers, epoxidized fatty acid methyl ester, also known as epoxy fatty acid ester, is favorable for application as an additive material in PVC, which...
Synthesis and Properties of Isosorbide-Based Eco-friendly
An esterified isosorbide with long alkyl-chain length was epoxidized to enhance its plasticizing properties and enable low-cost production; the high epoxidation degree (91%) indicated efficient...
Conversion of fatty acid methyl ester to epoxy plasticizer by
Among the alternatives of phthalates, epoxidized vegetable oil (EVO) or fatty acid alkyl esters (EFAAEs), typically epoxidized fatty acid methyl esters (EFAMs), are a type of bioplasticizer that can be produced from vegetable oil biomass or its derived FAAEs such as fatty acid methyl esters (FAMEs) which are also known as biodiesel.
- What is epoxy fatty acid methyl ester?
- Epoxy Fatty Acid Methyl Ester (EFAME),directly made from natural plant oil through etherification and epoxidation, is a kind of environmental epoxy plasticizer. It has very good process ability to PVC products with low cost, and it can partial or even totally replace phthalate plasticizer for PVC products.
- Can epoxidized fatty acid Isobutyl esters be used as biobased plasticizer in PVC?
- However, few studies on the preparation and application of epoxidized fatty acid isobutyl esters (Ep-FABEs) as the biobased plasticizer in PVC were reported. In this paper, a two-step approach, including transesterification and epoxidation, was adopted to prepare Ep-FABEs using biodiesel as the raw material, as shown in Fig. 1.
- What are biobased plasticizers?
- To date, biobased plasticizers mainly include epoxidized fatty acid methyl esters (Ep-FAMEs) , aliphatic diesters , epoxidized triglycerides , and citrate plasticizers .
- Does epoxidized fatty acid 2-ethylhexyl ester increase migration resistance?
- The obtained epoxidized fatty acid 2-ethylhexyl esters showed better migration resistance than that of Ep-FAMEs . The transesterification reaction proved to be a simple and efficient method to increase the molecular weight of Ep-FAMEs and hence improve their migration resistance.
- Why are EP-FAME fatty acid methyl esters so popular?
- Among them, Ep-FAMEs have received considerable attention because of its high plasticizing efficiency and low cost, which can be directly acquired from unsaturated fatty acid methyl esters by using percarboxylic acids or organic/inorganic peroxides , , , .
- Are EP-Fabes a good plasticizer for PVC industry?
- Moreover, Ep-FABEs exhibited better resistance to extraction and migration than another biobased plasticizer Ep-FAMEs. In summary, Ep-FABEs derived from renewable sources have good potential as an environmentally friendly plasticizer in PVC industry.
