Plasticiser loss is a topic frequently mentioned in discussions on the degradation of plastic artefacts in museum collections, particularly for plasticised poly (vinyl chloride) and
The reported occurrence of the two migration modes for different polymer−plasticiser systems (The division into the two migration modes is based on the main features at each temperature as reported.

This direction helps prioritize vulnerable objects and reduce plasticizer migration, loss, and subsequent plastic degradation over time. Plastics are made of polymers with additives such as colorants, heat stabilizers,
It’s not just about flexibility though. Plasticizer migration can cause other additives to migrate too. Typical examples of these additives are UV stabilisers or Anti-Oxidants. If plasticizer migration causes these additives to

where M t (μg/cm 2) is the cumulative mass of migration at time t (s), C 0 (μg/cm 3) is the initial mass content of each plasticizer in PVC and D (cm 2 /s) is the diffusion coefficient
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,

Although the UV-Vis method is not very common in studying plasticizer migration, a height a peak at 199 nm attributed to ester groups could provide the information about the occurrence of leaching. Both methods indicated DEHP as the
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

Plasticizer migration mechanism and structural changes of G50 starch ester nanocomposites were performed by mathematical models and instrumental analysis. The primarily occurring migration mainly in “plasticizer-rich” domains followed the Fick’s second law, in which the differential concentration inside and outside of the starch-based
