Plasma treatment reduces migration of plasticizers from blood
The researchers’ tests showed that plasticizer migration from soft PVC could be reduced by 95 percent. To determine the barrier effect, the treated PVC films are stored in n-decane, a solvent, for two hours to identify the quantity of migrated plasticizers. To test the long-term stability of the barriers, the treated soft PVC films were
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.
Common Signs Of Plasticizer Migration - Chaffee Industrial
The plasticizer, which makes PVC a flexible membrane, will react with residue from an older installation, causing it to leak. The migration weakens the bond causing it to crack or split and causes the PVC to lift around the edges. Regular inspections will help you spot this problem before it causes trouble.

Plasticizer migration occurs as a result of the PVC membrane formulation. Most PVC products, like PVC pipe, PVC trim, and PVC decking, are solid, rigid products. In order to make PVC a flexible membrane sheet, the formulation needs to be altered.
Plasticizers for PVC | POLYNT
Polymeric plasticizers: their main characteristic is the high migration resistance (both in contact with oils, fats and hydrocarbons, and with thermoplastic materials), a good resistance to high temperatures and a low volatility.
- 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.
- Do plasticizers migrate from PVC?
- These additives are supposed to stay in PVC for permanent flexibility, but unfortunately, they continue migrating from the coating matrix, leading to a series of consequences. A range of analytical methods for the determination of plasticizer migration from PVC synthetic materials is now available.
- 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.
- Why is plasticizer migration important?
- 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-eficient simulant of genuine leather.
- 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.
- Do plasticizers have migration resistance?
- Therefore, any emerging plasticizer that succeeds in this arena of inten-sive competition is required to demonstrate excellent migration resistance, a crucial indicator governing how the resulting PVC coating holds up against long-term service and low environmental impact [9, 10].
