PVC Plasticizers and Stabilizers Following Safer Sustainable
PVC (PolyVinyl Chloride) stabilizers such as lead, mixed metals, and tin traditionally represent the key critical additives used in PVC manufacturing to eliminate PVC plastic decomposition during the heating process.
Thermal stability of poly(vinyl chloride) with epoxidised
The suspension PVC–ESBO samples containing Calcium- and Zinc-stearate (CaSt 2 /ZnSt 2) and other traditional stabilizers were prepared by blending the dry ingredients i.e. PVC, lubricant (0.3 ph), and stabilizers for 2 min in a household mixer followed by adding the plasticizers and blending for another 2 min. The blends were then two-roll
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC
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 loss...

- 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.
- 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.
- 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).
- Does Esbo reduce thermal degradation of PVC?
- DSC analyses carried out on pure plasticizer showed the presence of crystalline polymorphism in ESBO. Therefore, it could be concluded that the thermal degradation of PVC is clearly limited by the addition of ESBO at amounts higher than 1–2 wt%, and especially if ESBO concentrations are in the range of values used for plasticizers (30–40 wt%).
- What is PVC Esbo used for?
- PVC–ESBO materials have shown some applications in food packaging, mainly in domestic films or as gaskets of lids for glass jars to form the airtight seal preventing microbiological contamination and providing easy opening. PVC usually contains 25–45 wt% when ESBO is used as plasticizer and 1–2 wt% if it is used as stabilizer , , , .
