A Strategy for Nonmigrating Highly Plasticized PVC
Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to
Plasticiser loss from plastic or rubber products through diffusion and
This type of mode-transition was also reported by Shashoua 34 for DEHP-plasticised PVC in closed and open environments at 70 °C. Audouin and Verdu 30 observed that both the initial plasticiser...
Methods for determination of plasticizer migration from polyvinyl
2 Test methods for 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.
Know your Plasticizers: A New Study on Plasticizer Migration
The plasticizers discussed in the study include DEHP and diisononyl phthalate ( DINP ), both of which were rated marginal for contact with three of the four non-PVC materials; and DPHP, which was found acceptable for contact with three of them.
Plasticizers for PVC | POLYNT
Plasticizers trimellitates: they are characterized by an excellent flexibility at low temperatures and high resistance to higher temperatures; they are molecules primarily used in the production of electrical circuit components, wiring cables, car interiors and machinery components used in the medical and scientific field.
- 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.
- 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.
- 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.
- 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.
- Do plasticizers migrate better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
