Thermal stability of poly(vinyl chloride) with epoxidised
Initial colour and colour after thermal ageing at 100 °C for 72 h of PVC–ESBO with different amounts of CaSt 2 /ZnSt 2 stabilizer. As mentioned above, ESBO is regarded as a co-stabilizer which synergizes with CaSt 2 /ZnSt 2 in traditional formulations. In PVC–ESBO, there are no such synergies.
UV and thermal stability of soft PVC plasticized with
In particular, the value of A NT for samples m5 and m20 is even lower than that measured for ESBO, which is usually considered as an efficient stabilizer for PVC. Therefore, PLACARD plays both roles in soft PVC, plasticizer and thermal and UV stabilizer, limiting the oxidation of PVC. Download : Download high-res image (108KB)

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 plasticizer....
- 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.

- 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.
- Can Esbo be stabilized without a stabilizer?
- The stabilizing mechanism of ESBO itself, without the addition of stabilizers, has also been investigated. Analyses with ion chromatography of ESBO extracted from PVC samples without stabilizer revealed that the chlorine content of ESBO had increased when ageing the sample.
- Does Esbo improve thermal behaviour of PVC-Esbo?

- Can epoxidised soybean oil be used as a primary plasticizer in PVC?
- 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 compared to a compound with PVC–ESBO only. Surprisingly, the addition of stabilizers seems to decrease the stability of PVC–ESBO.
