Mechanical and Thermal Properties of the Plasticized PVC-ESBO
he thermal and mechanical properties of plasticized PVC with epoxidized soya 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 transition temperature of PVC is a linear function of the epoxidization of ESBO plasticizer.

Mechanical and Thermal Properties of the Plasticized PVC-ESBO epoxidization; glass transition temperature; stabilizers; activation energy. ABSTRACT Key Words: The low thermal stability of polyvinyl chloride (PVC) has limit-ed the use of this polymer in indus-try. There has been many attempts to improve the thermal stability and
Stabilization Studies of Epoxidized Soybean Oil Plasticized PVC Films
This study showed that epoxidized soybean oil (ESBO) could be used as a primary plasticizer for PVC. They can be used to replace DOP up to 100%. Epoxidized soybean oil indicated the excellent properties as a co-stabilizer for PVC when used in combination with the Ca/Zn stearates.
Thermal stability of epoxidized soybean oil and its absorption and
From Figure 4, the T g of neat PVC is 80.77°C, which agrees reasonably well with the value of 83°C that has previously been reported for PVC. 44, 45 However, the T g of PVC plasticized with...
- 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 Esbo affect the glass transition temperature of PVC?
- The glass transition temperature of PVC is a linear function of the epoxidization of ESBO plasticiz- er. 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.
- Does dehydrochlorination influence the activation energies of PVC plasticized with Esbo?
- The thermal and mechanical properties of PVC plasticized with ESBO have been extensively studied, and the results demonstrated that the activation energies of stabilized PVC/ESBO is influenced by a dehydrochlorination reaction and further HCl evolution . ... Patrick Jerome. Gronlund

- Why is the plasticization time of PVC shorter than ESBO?
- These results can be explained by the lower viscosity of DOP which penetrates the outer surface of PVC faster than ESBO in the first stage of plasticization. Therefore, the plasticizing time of PVC by DOP is shorter than that by ESBO [11, 18].
