Spectrophotometric characterization of plasticizer migration
Although, linear plasticizers e.g. BIO and DOA have higher compabilities with PVC, a branched plasticizer e.g. TOTM showed higher mechanical properties. Moreover, a new spectrophotometric...
Methods for determination of plasticizer migration
Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those

- Can spectrophotometric method be used to monitor plasticizer migration?
- The rates of weight loss for PVC films performed in the isobutanol medium are also correlated with the results obtained from the spectrophotometric method. Therefore, the developed method based on the spectrophotometer can be used to monitor the plasticizer migration. 4. Conclusion
- How is plasticizer migration determined?
- A new spectrophotometric method for the determination of plasticizer migration. Chemical structure is the prominent determinant for the migration of plasticizers. Plasticized polyvinyl chloride (PVC) is one of the most commonly used material in the manufacture of artificial leather because of its flexibility, high durability and low cost.
- How can we measure plasticizer migration in coextruded PVC pipes?
- Technologically relevant for plasticizer migration studies in coextruded PVC pipes. This study introduces and validates an effective approach for monitoring the plasticizer amount and its concentration profile in polyvinyl chloride (PVC) formulations. The method combines gravimetric measurements with confocal Raman depth profiling analysis.
- How do we detect plasticizer migration from PVC synthetic materials?
- To this end, this review is compiled as a general review of the methods now available for detect-ing plasticizer migration from PVC synthetic materials via three diferent mechanisms (i.e., volatilization, exu-dation, and extraction), with an emphasis on the instru-mentation, methodology, advantages, and limitations of each method.
- Does molecular weight affect plasticizer migration rate?
- Other used plasticizers have very similar molecular weights which hinders the studying effect of molecular weights on the migration rate. Plasticizer migration from PVC films can be also studied by the leaching test using two different solvents, water and isobutanol [31, 32].
- Do plasticizers migrate from PVC films?
- The migration of plasticizers from PVC artificial films was also evaluated in terms of the weight loss percentages. PVC films (3.5 g), which are used in artificial leathers, including 60 phr of different plasticizers were soaked in 400 mL water or isobutanol solutions. After 48 h, the samples were wiped up and dried in oven at 40 °C for 2 h.
