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 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

ERBO presented fairly good incorporation and plasticizing performance, as demonstrated by the results of mechanical properties, exudation, migration tests, thermal stability by thermogravimetric analysis, T g values as shown by differential scanning calorimetry, replacing about 60 % of the total plasticizer. Introduction
Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
- 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 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.
- 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.
- 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.
- 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 increase thermal stability?
- 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. 1. Introduction
