Plasticiser loss from plastic or rubber products through diffusion and
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
Methods for determination of plasticizer migration from polyvinyl
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.
A Strategy for Nonmigrating Highly Plasticized PVC
To observe the migration of plasticizers, the migration behaviour of the new DOP-like plasticizer in PVC was tested through extraction experiments with n-heptane at room temperature 35....
Migration of plasticizers from poly(vinyl chloride) and multilayer
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.).
Migration of plasticizers from plasticized polyvinyl chloride films
The migration of plasticizers [EDOS, di(2-ethyl hexyl) o-phthalate, di-n-butyl o-phthalate] from unfilled and chalk-filled polyvinyl chloride films plasticized with individual and binary plasticizers was studied by gravimetric analysis and IR spectroscopy. The intermolecular interaction of components in model systems was studied by IR spectroscopy and isothermal calorimetry.
- 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 MPVC to poly(dimethylsiloxane) via skin?
- There is a potential risk of exposure to PAEs from household PVC articles via skin. In the present study, the migration of plasticizers from modeled and commercial polyvinyl chloride (mPVC and cPVC, respectively) to poly (dimethylsiloxane) via artificial sebum was assessed to mimic the dermal migration of plasticizers.
- How do plasticizers migrate from PVC synthetic materials?
- In general, plasticizer migration from PVC synthetic materials can proceed via three diferent mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- What determines the extraction and migration of plasticizers in PVC?
- The extraction is mainly determined by the solubility of plasticizer in the medium, and migration is closely related to the compatibility between plasticizer and PVC. The diffusion of plasticizers in PVC can be carried out in the medium that will not infiltrate into the polymer or in the medium infiltrating the polymer.
- 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 do PVC plastics migrate Paes?
- Dermal migration of PAEs from PVC plastics via artificial sebum is assessed. Diffusion and migration are increased with sebum mass and temperature, while decreased with pressure and molar mass of PAE. Diffusion of DINP in soft PVC (cPVC) is higher than hard PVC (mPVC) sample tested.
