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.
Migration of epoxidized soybean oil from polyvinyl chloride
Epoxidized soybean oil (ESBO) has been used in polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) food packaging cling film as a plasticizer and stabilizer. The aim of this study was to investigate the migration of ESBO from PVC/PVDC cling film, based on gas chromatography mass spectrometry (GC
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...
Thermal stability of poly(vinyl chloride) with epoxidised
Epoxidised soybean oil (ESBO) has been tested as a primary plasticizer in suspension PVC. The stabilization of the material with different traditional stabilizers has been evaluated and...
- Does dibenzoylmethane stabilize epoxidized soybean oil (ESBO) Plasticized PVC?
- The present work focuses on the development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of calcium/zinc stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM). The DBM which has dual property of a UV stabilizer and heat stabilizer was varied from 0 to 10 phr.
- Can Esbo be used for PVC stabilization?
- Formulations based on PVC with different amounts of ESBO (from 30 to 50 wt%) were fully characterized showing good compatibility and a clear increase in thermal stability. An evaluation of the use of ESBO for PVC stabilization in commercial lids was carried out by using thermogravimetric analysis (TGA).
- 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.
- What is epoxidized soybean oil (ESBO)?
- Epoxidized Soyabean Oil (ESBO) is a renewable and non-toxic chemical compound widely used as a plasticizer and stabilizer in PVC compounds, food packaging, and many other industrial applications. It is derived from soybean oil and has excellent heat and light stability, making it a preferred choice for many industrial applications.
- 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 , , , .
- Does Esbo improve thermal behaviour of PVC?
- Addition of ESBO improves thermal behaviour of PVC. The higher activation energies of Ca-Zn, Ba-Zn stabilizers are responsible for the stability of PVC-ESBO. The epoxidization level of ESBO also improves the mechanical properties and thermal stability of PVC. epoxidization; ABSTRACT Content may be subject to copyright.
