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
Common Signs Of Plasticizer Migration - Chaffee Industrial
When the plasticizer leaks from a PVC roof, it will cause cracks, splits, and welded sections to break apart. Combining plasticizer migration with foul weather means disaster for your roof. Early spotting of the common signs of plasticizer migration helps protect your roof. Let’s take a look at some of the telltale indicators.
Plasticizer Migration - an overview | ScienceDirect Topics
Plasticizer migration from one material to another causes problems with their performance.1,4 Figure 10.65 shows that plasticizer migration increases with the increase in the plasticizer concentration in PVC. The migration process follows Fickian diffusion and can be approximated from the following equation: Sign in to download full-size image
Know your Plasticizers: A New Study on Plasticizer Migration
To address this phenomenon, Teknor Apex (Pawtucket, RI) has published a study focusing on plasticizer migration, which can affect a range of medical device components, including connectors. "Most PVC applications are connected to a rigid non-PVC material, and that rigid material typically is more attracted to the plasticizer than the PVC device

- Why is plasticizer migration a problem for PVC?
- Plasticizer migration from a PVC item to its surroundings can lead to problems such as the modification of the PVC's flexibility and contamination of the media in contact with PVC.
- Do plasticisers migrate from polymers to a gas phase?
- This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service temperature conditions and during accelerated ageing and testing.
- 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 polymeric plasticizers migrate?
- The related researches on polymeric plasticizer and macromolecule plasticizers mainly focus on molecular structure design and migration in different solvents [, , ]. It is effective to prevent plasticizers migration via introducing branched chains and polar groups in their chemical structure [78, 79].
- What is the loss of plasticizer?
- The loss of plasticizer includes gas volatilization, liquid extraction and solid migration according to the difference of the external medium. In order to express convenience, the loss of plasticizer in the three ways is collectively referred to as migration. Plasticizer migration has been discovered and concerned for half a century.
- 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.
