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.
Characterization and thermal stability of poly (vinyl
ESBO was detected in all materials and their thermal stability was highly dependent on the plasticizer concentration. Most of them showed a significant increase in thermal degradation temperatures, permitting their use in food processing at high temperatures without risk of degradation.

The plasticizers (ESO or ESBO) were respectively compounded with PLA at 10, 20, 30, and 40 wt%. Mechanical (tensile and Shore D hardness), thermal (differential scanning calorimetry (DSC), thermogravimetric analysis (TGA)) and morphological properties (optical microscopy and scanning electron microscopy (SEM)) were characterized.

The plasticizer (DOP/ERBO) was compounded with PVC resin in a two-roll mill at temperature of 160 °C for 2 min. The sheets were compression molded at the operating temperature of 160 °C for 7 min. Similarly plasticizer (DOP/ESBO) was also compounded with PVC resin as shown in Table 2. Table 1 Formulations of PVC resin with plasticizer (DOP/ERBO)
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]
- 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 stabilized without a stabilizer?
- The stabilizing mechanism of ESBO itself, without the addition of stabilizers, has also been investigated. Analyses with ion chromatography of ESBO extracted from PVC samples without stabilizer revealed that the chlorine content of ESBO had increased when ageing the sample.
- What is Esbo (epoxidized soybean oil)?
- ESBO (Epoxidized Soybean Oil) is a widely used plasticizer and stabilizer in the polymer industry, known for its unique characteristics and versatile applications. Here are some key characteristics of ESBO: ESBO functions as a plasticizer, imparting flexibility, softness, and elongation to polymers such as PVC (polyvinyl chloride).
- Why is Esbo a good material?
- ESBO exhibits excellent heat stability and thermal resistance, making it suitable for applications requiring exposure to elevated temperatures. It helps maintain the integrity and mechanical properties of polymer products under thermal stress and processing conditions.
- Is Esbo biodegradable?
- It complies with regulatory standards such as FDA (U.S. Food and Drug Administration) regulations and European REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) directives. ESBO is derived from natural soybean oil and is biodegradable, making it an environmentally friendly alternative to conventional plasticizers.
- What are the characteristics of ESBO?
- Here are some key characteristics of ESBO: ESBO functions as a plasticizer, imparting flexibility, softness, and elongation to polymers such as PVC (polyvinyl chloride). It improves the processability and workability of PVC formulations, making them easier to process and mold into various shapes and products.
