Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Epoxidized vegetable oils (ESBO) originating from soybean oil, is known as secondary plasticizer and a secondary stabilizer in PVC. It showed limited compatibility with PVC and low plasticization efficiency, due to the unreacted double bonds and hydroxide groups formed during the epoxidation [ 37 , 38 ].
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.

Mechanical and Thermal Properties of the Plasticized PVC-ESBO
The activation energies of stabilized PVC/ESBO is also influenced by dehydrorochlo- rination reaction and HCl evolution. Addition of ESBO improves thermal behaviour of PVC. The higher...
- 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.
- 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).
- 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.
- 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.
- Which polymers are compatible with Esbo?
- ESBO is compatible with a wide range of polymers, including PVC, polyethylene, polypropylene, polystyrene, and various elastomers. It blends easily with polymer matrices, ensuring uniform dispersion and consistent performance in plastic formulations.
- 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.
