Bioplasticizer - an overview | ScienceDirect Topics
Levulinic acid can be extracted from cellulosic materials in biomass. Segetis Inc. has developed technology to react this acid with an epoxide producing a ketal. If a fatty acid ester, such as an alkyl epoxy soyate, is used as the epoxide source, materials are produced that can be used as plasticizers [39].
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, whereas the epoxide group can scavenge the
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...
Epoxidized methyl ricinoleate bio-plasticizer with a pendant
Processing polyvinyl chloride (PVC) artificial material requires plasticizer that softens the PVC coating. Currently, utilizing unsaturated fatty acid methyl esters to obtain epoxidized fatty acid methyl ester (EFAME) bio-plasticizers constitutes an environmentally responsible solution to substitute conventional ortho-phthalates that are endocrine disruptors or probable carcinogens. However
EPOXY FATTY ACID METHYL ESTER
Epoxy fatty acid methyl ester (EFAME) is a kind of plasticizer with epoxy groups in the molecular structure. In PVC resin processing industry, EFAME not only plasticize PVC, but also stabilize the active chlorine atoms in the chain of polyvinyl chloride. The epoxy groups in the structure can absorb hydrogen chloride degraded by light and heat
