Mechanical and Thermal Properties of the Plasticized PVC-ESBO
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-...
Effect of the individual and combined use of cardanol-based
Addition of a small amount of ESBO as a secondary plasticizer resulted in enhanced tensile modulus and strength while maintaining high elongation. Thermal aging tests also revealed that ECA was more effective in preserving mechanical properties with or without ESBO than DOP. Finally, CA and ECA had higher leaching stability than DOP.

to those of DOP p conclusion that BE can be used as a co ESBO upto wt. 65% to replace DOP. ABSTRACT Studies showed that phthalate plasticizers are carciogenic. The concerns raised about toxicity led to a large demand of producing non- toxic and bio- based plasticizers. Currently, ESBO can only replace 30% DOP in the PVC formulations.
Epoxidized Linseed Oil - an overview | ScienceDirect Topics
7.24.3.1 Epoxy Esters. ESBO and epoxidized linseed oil are used as lubricants and costabilizers to improve heat stability of PVC articles, paints, and coatings. At high concentrations, there are risks of development of incompatibility with PVC during aging, leading to migration and tacky surfaces in the presence of sunlight.
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC
It is better to replace DOP with ESBO, as there is no antiplasticization. Besides, for every Phr of DOP the VST is reduced by 3.5 deg C per Phr as against 1.5 deg C for ESBO. It is always...
- Can Esbo be used as a secondary plasticizer?
- Thus, to investigate the synergetic effects of combining DOP or cardanol-based plasticizers with ESBO as a secondary plasticizer, 5 phr of ESBO was added to each sample of PVC/DOP (50), PVC/CA (50) and PVC/ECA (50). The Young's modulus and tensile stress of all PVC/DOP (50)+ESBO (5) and PVC/CA (50)+ESBO (5) samples were improved.
- Can cardanol based plasticizers be combined with epoxidized soy bean oil?
- Although cardanol-based plasticizers including cardanol acetate (CA) and epoxidized cardanol acetate (ECA) have individually been studied on their plasticization effects for PVC as well as thermal and leaching stabilities, the combinational use of cardanol based-plasticizers with epoxidized soy bean oil (ESBO) has not previously been investigated.
- Are DOP and ECA compatible with PVC resin?
- Therefore, DOP and ECA have good compatibility with PVC resin; however, PVC/ESBO and PVC/CA composites have limited compatibility, resulting in the overlapping tan δ peaks for the plasticizer-rich phase at a lower temperature and the PVC-rich phase at a higher temperature.
- Are cardanol based plasticizers good?
- The reported cardanol-based plasticizers have good plasticizing effects, but there are some limitations and a lack of research in terms of thermal stability and leaching resistance.
- Is cardanol glycidyl ether a biobased plasticizer?
- A novel biobased plasticizer of epoxidized cardanol glycidyl ether: synthesis and application in soft poly (vinyl chloride) films Effect of the epoxidation yield of a cardanol derivative on the plasticization and durability of soft PVC Polym.
