Characterization and thermal stability of poly (vinyl
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.

Performance evaluation of new plasticizers for stretch PVC
Abstract. Six stretch PVC films have been formulated to have Shore A hardness of approx. 80 and nominal thickness of 15 μm with the aim of evaluating the performance of plasticizers from renewable and non-renewable sources for stretch PVC films intended to be employed as packaging. The reference film was produced with DEHA and ESBO, while the
Epoxidized rice bran oil (ERBO) as a plasticizer for poly
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)
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...
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC
During processing, ESBO helps to reduce viscosity of PVC. The effect is more visible in smoother rolling bank in calendaring process. As a plasticizer: ESBO acts as a secondary...
- 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.
- 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.
- 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.
- Which stabilizer is responsible for the stability of PVC-Esbo?
- 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. activation energy.
- 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 , , , .
- How does epoxidization affect PVC Esbo?
- bean oil (PVC-ESBO) are studied. The repulsive interactions are used to explain the effect of epoxidization on the modulus of PVC with ESBO and plasticizer. The glass er. The activation energies of st abilized PVC/ESBO is also influenced by dehydrorochlo- rination reaction and HCl evolution. Addition of ESBO improves thermal behaviour of PVC.
