Performance assessment of polyvinyl chloride films
Migration stability test. PVC films were tested for the determination of migration stability of plasticizer in different solvents for 72 h and obtained results are represented in Fig. S9. PVC film plasticized with DOP (PVC A) exhibits maximum migration in each of the solvent. The migration is decreased as the concentration of ECLO is increased.
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. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those
One-pot and industrial manufacturing of cardanol-based
Sun (Sun et al., 2025) developed a star-poly(vinyl chloride) plasticizer for PVC through the production of RAFT agent under ice bath and then polymerization with vinyl chloride. The migration resistance and plasticization of PVC sample plasticized by star-poly(vinyl chloride) were fully beyond those of PVC blended with DOP.
Migration of plasticizers from poly(vinyl chloride) and
The migration of DEHP in PVC grain exceeded the maximum regulated level of 5000 μg/kg, whereas the levels were much lower in films. In new PVC bags, DEHP was the only compound detected at 4.31 ± 0.5 μg/L in NaCl 0.9% and 4.29 ± 0.25 μg/L in glucose 5% serums, whereas the levels increased 10 times in three-year shelf-life bags.
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
- 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 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 improve the migration resistance of plasticized PVC material?
- This indicates that a moderate increase in the relative molecular weight of the plasticizer can effectively improve the migration resistance of the plasticized PVC material, a finding consistent with the results from the resistance tests. There has been no clear evidence observed regarding the plasticization process of plasticizers in PVC.
- 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.
- 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.
- What is the migration of plasticizer?
- Migration of the plasticizer ues by a whole order of magnitude. The migration of at the interface . values. Since only DOP after a long-term aging. cross-linking agent for PVC dry blends. The increase of rable cross-linking densities. ing the mechanical properties of flexible PVC.
