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.
Properties Investigation of Epoxidized Sunflower Oil as
The comparison of ESO to ESBO at the optimum plasticizer content (20 wt%) shows that ESBO presents best elongation at break because of its lower molecular and its good compatibility with PLA, while ESO 6.5 % exhibits better elongation at break than ESO 5.5 %. The increasing in films elongation can be explained by the fact that plasticizers
Epoxidized Soybean Oil - KH Chemicals
Epoxidized Soybean Oil Epoxidized soybean oil, better known by its acronym, ESBO, is a plasticizer used in polyvinyl chloride (PVC) plastics. It serves as a plasticizer and as a scavenger for hydrochloric acid liberated from PVC when the PVC undergoes heat treatment.

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.
