Effect of Solvent (Plasticizers) on PVC Degradation - Zaikov
Both plasticized (semi-rigid and flexible) PVC materials as well as PVC in solutions, the rate of their thermal degradation and effective stabilization are caused by essentially different fundamental phenomena in comparison to aging of PVC in absence of the solvent.

Plasticiser loss from plastic or rubber products through
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
- What is the degradation mechanism of PVC?
- In actual field, the degradation mechanism of PVC is a great concern to estimate the service periods of the product under weathering condition as well as under thermal aging condition. The large number of works was carried out on this topic , , .
- Does plasticizer concentration affect mechanical properties of plasticized PVC?
- The plasticized PVC contains much amount of plasticizer in its component. The plasticizer concentration relates to mechanical properties and molecular motion closely. The influences of the plasticizer concentration on the mechanical properties have been studied .
- What is the degradation mechanism of plasticized PVC under weathering test?
- Degradation mechanism of the plasticized PVC under weathering test. The contact surface area with sprayed water increased by forming voids, and the flow out of plasticizer can be clearly advanced. The aggregation of PVC was promoted by the decrease of plasticizer. According to the result of pulse NMR, the FT 2S increases gradually.
- Is EPO a plasticizer for PVC?
- The results indicate that EPO is a potential plasticizer for PVC when pure and, by replacing 50% of DOCH, the PVC compound shows similar properties to pure DOCH, but better elongation at break and thermal stability. 1. Introduction
- Does plasticizer migration affect dynamic friction compared to rigid PVC?
- Plasticizer migration towards the interface caused an increase of dynamic friction compared to that of the reference rigid PVC.Vickers microhardness hVickers values of rigid PVC sheets decreased due to plasticizer surface absorption. POLYM. ENG.
- Are flexible poly (vinyl chloride) phthalate based plasticizers toxic?
- Uses of flexible poly (vinyl chloride) (PVC) are restricted by plasticizer migration affecting material properties. Moreover, the use of phthalate-based plasticizers is being questioned worldwide because of their potential toxicity to humans and environment.
