Synthesis and Application of Environmental Castor Oil Based Polyol
The use of vegetable oil based plasticizers can create new application for plasticized poly(vinyl chloride) (PVC) materials. In this study, novel environmental castor oil based polyol esters (COPE-1, ECOPE-1, COPE-2 and ECOPE-2) were synthesized and characterized with FT-IR and 1H NMR.

New Vinyl Epoxy Plasticizers | C&EN Global Enterprise
The compounds, for which peracetic acid is the epoxidizing agent, may answer the crying need for a greater variety of epoxy plasticizers and stabilizers. To date only two epoxy classes have commercial status: epoxy fatty acid esters and the glycidyl ethers. FMC's Frank P. Greenspan estimated to the Division of Paint, Plastics, and Printing Ink

Epoxidized esters of palm olein as plasticizers for poly(vinyl chloride
Long chain epoxy esters were less compatible while their short chain counterparts were too volatile for thermal stability. Epoxy butyl esters of palm olein were found to be most promising. The solubility parameters δ for a series of oleates, palmitates and epoxy esters were calculated using Small's method with Fredors' molar volume.
- Are epoxidized cardanol ester stabilizers suitable for PVC films?
- In this work, two different epoxidized cardanol ester stabilizers were synthesized, and their structures were characterized. Moreover, their synergistic plasticizing and thermal stabilization effects on PVC were studied, and PVC films with excellent mechanical and thermal stability were prepared.
- Does epoxidized cardanol glycidyl ether improve thermal stability of PVC?
- They found that compared with PVC plasticized by DOTP and DINP, PVC plasticized by CGE showed better thermal stability. Then, they continued to study the effect of epoxidized cardanol glycidyl ether (ECGE) on the plasticization and thermal stability of PVC [ 17 ].
- Are organic heat stabilizers suitable for PVC?
- In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
- Does polyvinyl chloride (PVC) need a heat stabilizer?
- The development of a heat stabilizer with good thermal stability, plasticizing performance, and migration resistance for polyvinyl chloride (PVC) is still a notable challenge.
- Why do we use heat stabilizers in PVC films?
- In addition, heat stabilizers can also act as a plasticizer to increase the movement of the molecular chain. If PVC chains can easily adjust the conformation, it can convert the internal heat energy into kinetic energy, which makes the plasticized PVC film with superior thermal stability.
- Does stabilizer improve transparency of PVC film?
- The transparency of the film was enhanced dramatically after the addition of stabilizer between 400 and 550 nm. This was because the stabilizer could improve the initial transparency of the PVC film by replacing the unstable chloride atoms in the PVC chains, which resulted in a significant improvement of the initial transparency.
