Nontoxic bio-plasticizers for PVC as replacements
Another vegetable based plasticizer is epoxidized soybean oil (ESBO), a kind of renewable oil with viscosity 35 cPs; it has been long known as secondary plasticizer and a secondary stabilizer in PVC. ESBO is available with iodine value as low as 1 g l2/100 g, i.e. ≈ 0.04 mol double bonds in each molecule of ESBO.
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]
Thermal stability of poly(vinyl chloride) with epoxidised
The use of epoxidised soybean oil (ESBO) as secondary plasticizer and secondary stabilizer in PVC has been long known. The level of addition is typically 1–5 ph. During the 1950s and 1960s, ESBO was tested as primary plasticizer at higher levels of addition, around 50 ph, but with contradictory results.
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-MS). The specific migration of ESBO was evaluated using various food simulants (water, 4%
