Migration of Plasticizers from Polyethylene Terephthalate and Low
Migration Kinetics of PAEs From Plastic Bottle to Water. In order to address the possible migration of plasticizers depending on the storage time and temperature for a longer duration, kinetics models were used. The data obtained were fit into three kinetic models, linear, and exponential models as given elsewhere (Luo et al. 2018).
Plasticiser loss from plastic or rubber products through diffusion and
The migration of plasticiser from polymers to a gas phase is a two-step process that includes diffusion from the polymer bulk to the surface followed by evaporation from the surface to the...
Simultaneous improvement of the plasticization, mechanical and
Because of the rigidity and brittleness of PVC, plasticizers are developed and blended with PVC to improve its processability (Adams et al. 2015; Bocqué et al. 2018; Cui et al. 2025 ). Phthalates are a kind of low molecular weight plasticizers that have been widely studied due to their high compatibility with PVC (Earla and Braslau 2014 ).
Sustainable Micro and Nano Additives for Controlling the Migration of a
The results confirm also that 4 wt % of 2AV is not a sufficient quantity to efficiently limit plasticizer migration; on the other hand, passing from 4 to 7 wt %, very good results are achieved. For longer times, the different behavior to the plasticizer migration for the three types of calcium carbonate emerges.
Methods for determination of plasticizer migration from polyvinyl
Of course, plasticizer exudation entails no a solid surface that remains close contact with the PVC coating. When a plasticized PVC coating is stressed in compression by bending it through 180°, one way to relieve the stress is by migration of the plasticizer from the compressed area to the area in tension.
- How can plasticizer migration be reduced?
- The measures taken for reducing plasticizer migration should suppress at least one out of three migration paths: diffusion towards the pPVC surface, passage through the surface, and penetration to the neighbouring medium. In principle, there are five possibilities to reduce the dangerous impact of migrated plasticizers on human health:
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
- 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 do plasticizers have a high migration resistance?
- A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance. As expected, the migration resistance was significantly higher than in films plasticized by DEHP because of the higher molecular weight of alkyl-HPGs .
- 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.
- How do nanoparticles reduce plasticizer movement?
- Adding nanoparticles seems to be another way to restrict plasticizer migration . Nanoparticles easily adsorb other substances on the surface due to a large portion of unsaturated bonds on their surface. Consequently, the restricted mobility of nanoparticles substantially reduces movement of plasticizers.
