Migrability of PVC plasticizers from medical devices into a
The plasticizers in the PVC matrix can leach out into the infused solutions and may enter into contact with the patients. In order to assess the risk of patient exposure to these plasticizers we evaluated the migration performance of DEHP, DEHT, DINCH, and TOTM using a model adapted to the clinical use of the MDs.
Migration of plasticizers from PVC medical devices: Development of an
Abstract. Alternatives to DEHP plasticizers are used in various PVC medical devices (MD) for infusion. As they are able to migrate from these MDs into infused solutions, they may come into contact with patient. Different and specific clinical parameters influence their migration in at-risk situations such as infusion.
Eastman Plasticizers for PVC
Eastman 168 non-phthalate plasticizer has been safely used in PVC for generations. With proven performance as an alternative to DOP/DEHP and DINP, Eastman 168 can be used for a wide variety of flexible PVC applications. In many cases, our non-phthalate solutions can be a drop-in replacement for traditional phthalates in your manufacturing
- Can PVC plasticizers migrate to a polymer in contact with flexible PVC?
- The ability of different PVC plasticizers to migrate towards a polymer in contact with flexible PVC has been investigated. A procedure based on the monitoring of the plasticizer concentration by infrared spectroscopy has been employed.
- Why is plasticizer migration a problem?
- The plasticizer migration from the plastic item to its surroundings may involve the appearance of problems, namely the modification of flexibility of the PVC and the contamination of the media in contact with PVC.
- 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.
- 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.
- 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.
- Are plasticizers in the PVC matrix a risk factor for patient exposure?
- The plasticizers in the PVC matrix can leach out into the infused solutions and may enter into contact with the patients. In order to assess the risk of patient exposure to these plasticizers we evaluated the migration performance of DEHP, DEHT, DINCH, and TOTM using a model adapted to the clinical use of the MDs.
