Study of the migration of PVC plasticizers - ScienceDirect
The study of the pyrolysis behaviour can be used in order to evaluate the amount of plasticizer migrated. Several samples must be analysed in order to obtain reliable results. The behaviour of plasticizers of different chemical families (i.e. phthalates and citrates) and molecular weights, has been studied. Although the plasticizer loss is not
Study of the migration of PVC plasticizers - ScienceDirect
In the present work, an experimental method has been developed and applied to evaluate the capacity of migration of plasticizers from plasticized PVC typical in rotational moulding applications. Phthalates have shown a single but broad process of plasticizer evolution when heated in a thermobalance under nitrogen atmosphere.

The aim of this paper is the determination of the migration and biodegradation of the PVC additives in the soil. Epoxidized Sunflower Oil (ESO) was used as a thermal organic co-stabilizer for PVC; it… Expand Reducing the migration of additives from plasticised poly (vinyl chloride) M.O. Boussoum, Y.R.

Migration of plasticizers from poly(vinyl chloride) and
Migration of plasticizers from poly(vinyl chloride) and multilayer infusion bags using selective extraction and GC-MS Flexible poly(vinyl chloride) (PVC) is widely used in the pharmaceutical industry for the manufacture of medical devices (tubes, probes, bags, primary packaging, etc.).
Methods for determination of plasticizer migration
In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- Can plasticizers migrate from flexible PVC parts to other media?
- An accelerated method has been set up in order to study the capacity of migration of different commercial plasticizers from flexible PVC parts towards other media kept in contact with it; in this case, polystyrene (PS) has been used as example.
- Why is extraction and migration of PVC plasticizers important?
- The study of the extraction and migration of PVC plasticizers is of great importance for several reasons. Extraction can occur in PVC films in contact with food, in bags or pipes in contact with biological fluids, such as blood, or even when a child could chew a PVC toy.
- Does PBA absorption affect plasticizer migration from flexible PVC?
- Integrating the profiles in terms of weight ratios, it is found that DEHP is adsorbed 300 % more than PBA, which justifies that gravimetry is insensitive towards PBA absorption. 4. Conclusions In this study, the plasticizer migration from flexible PVC in contact with rigid PVC sheets was investigated.
- 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.
- Does plasticizer migration cause premature coating failure?
- Journal of Leather Science and Engineering 4, Article number: 8 (2022) Cite this article 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.
- 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 detecting plasticizer migration from PVC synthetic materials via three different mechanisms (i.e., volatilization, exudation, and extraction), with an emphasis on the instrumentation, methodology, advantages, and limitations of each method.
