Migration of epoxidized soybean oil from polyvinyl chloride
Epoxidized soybean oil (ESBO) has been used in polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) food packaging cling film as a plasticizer and stabilizer. The aim of this study was to investigate the migration of ESBO from PVC/PVDC cling film, based on gas chromatography mass spectrometry (GC
Characterization and thermal stability of poly(vinyl chloride
Phthalates can be replaced by other harmless and environmentally friendly plasticizers, such as epoxidized soybean oil (ESBO), which has been also proved an efficient stabilizer for PVC helping to prevent degradation during processing.
Epoxidized soybean oil
ESBO is one of the additives in the PVC gasket. It serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally, e.g. when the gasket is applied to the lid and food product undergoes sterilization. [5] ESBO is also used in PVC cling films for wrapping foods and toys. Safety [ edit] Food [ edit]
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC PROCESSING AND
ESBO acts as a secondary plasticizer. Usually all plasticized compounds contain 5 phr ESBO. Beyond 5 phr, electrical properties are also impaired. ESBO/ELSO has excellent resistance to...
Epoxidized rice bran oil (ERBO) as a plasticizer for poly(vinyl
Epoxidized soybean oil (ESBO) and other epoxidized vegetable oils have found extensive applications in the industry as stabilizers and plasticizers into PVC matrices . Rice bran oil is one such naturally occurring non-toxic edible oil, having ~75 % unsaturated fatty acid composition, which can be utilized for various applications in polymer industry.
- Does dibenzoylmethane stabilize epoxidized soybean oil (ESBO) Plasticized PVC?
- The present work focuses on the development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of calcium/zinc stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM). The DBM which has dual property of a UV stabilizer and heat stabilizer was varied from 0 to 10 phr.
- Is Esbo a sustainable plasticizer?
- ESBO is derived from natural soybean oil and is biodegradable, making it an environmentally friendly alternative to conventional plasticizers. It reduces the environmental impact of plastic products and supports sustainable manufacturing practices.
- Can Esbo be used as a primary plasticizer for PVC plastisols?
- ESBO is usually mixed with co-plasticizers, which could be a reasonable practice used by industry in order to fulfil the specific migration limits of each plasticizer. However, since ESBO was seen to play a role in thermal stability of PVC it could be a good alternative as a primary plasticizer and/or stabilizer for PVC plastisols.
- Does Esbo improve thermal behaviour of PVC?
- Addition of ESBO improves thermal behaviour of PVC. The higher activation energies of Ca-Zn, Ba-Zn stabilizers are responsible for the stability of PVC-ESBO. The epoxidization level of ESBO also improves the mechanical properties and thermal stability of PVC. epoxidization; ABSTRACT Content may be subject to copyright.
- Can epoxidised soybean oil be used as a primary plasticizer in PVC?
- Epoxidised soybean oil (ESBO) has been tested as a primary plasticizer in suspension PVC. The stabilization of the material with different traditional stabilizers has been evaluated and compared to a compound with PVC–ESBO only. Surprisingly, the addition of stabilizers seems to decrease the stability of PVC–ESBO.
- Can Esbo be used for PVC stabilization in commercial lids?
- An evaluation of the use of ESBO for PVC stabilization in commercial lids was carried out by using thermogravimetric analysis (TGA). ESBO was detected in all materials and their thermal stability was highly dependent on the plasticizer concentration.
