Effects of Plasticizers and Stabilizers on Thermal Stability
The study was focused on the choosing of plasticizers and stabilizers for improving thermal stability of polyvinyl fluoride (PVF) during the thermoplastic processing. Five kinds of organic esters as plasticizers for PVF were evaluated.

Five kinds of organic esters as plasticizers for PVF were evaluated. The results showed that dimethyl phthalate (DMP) had better compatibility with PVF and phase separation didn't occur up to a relatively high concentration level

Synthesis and application of a novel environmental C26
The epoxy groups of the epoxidized plant oil-based plasticizers mentioned above can act as HCl scavengers and co-stabilizers to bring thermal stability to PVC . The present work, therefore, means to develop a novel, plant oil-based plasticizer with esters acting as cohesive blocks and functional alicyclic and epoxy groups.
Heat Stabiliser - an overview | ScienceDirect Topics
Stabilizers are ‘intentional additives’ used to prevent environmental effects (of heat, UV light, etc.) on the polymer. They are added to plastics to afford protection against heat (thermal), UV and mechanical degradation of the polymer during both processing and use.
- Can biobased plasticizer be used as a heat stabilizer?
- The plasticizing effect of single biobased plasticizer is not good. Biobased plasticizer with synergistic effects is required. There exists the trade-off effect between the molecular weight and the compatibility. Epoxidized isosorbide ester can be used as a heat stabilizer. The authors declare that they have no conflict of interest.
- 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.
- Why do we use heat stabilizers?
- Because the thermal stabilizer has epoxy groups, which can react with the hydrogen chloride produced by the thermal degradation of PVC, so as to inhibit the thermal degradation of PVC and stabilize PVC. In addition, heat stabilizers can also act as a plasticizer to increase the movement of the molecular chain.
- How do plasticizers affect tensile strength?
- In general, yield and tensile strength of PLA decreased, and fractured strain increased with the addition of plasticizers. Further increments in elongation at break obtained as plasticizer content increased. Over time, the tensile modulus increased and the elongation at break decreased in all plasticized PLA blends.
- 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.
- 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.
