A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The...

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
Plasticiser loss in heritage collections: its prevalence
Plasticiser migration occurs alongside the deacetylation of CA; although, its relative rate, importance, and impact is understudied. For PVC, evidence of both dehydrochlorination and plasticiser migration have been observed in collections. Thermal and/or photo-oxidative degradation mechanisms have been extensively studied [ 28, 29, 30 ].
- 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.
- Do plasticizers migrate?
- 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. As a comparison, migration of DOP was also measured under the same conditions.
- 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 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.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- 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.
