Plasticiser loss from plastic or rubber products through
The plot is simplified and limited to the following special cases: (1) the diffusivity in the plot is taken as the average of the concentration-dependent diffusivity, (2) the system exists above...
Migration of Monomeric and Polymeric PVC Plasticizers - Springer
This paper summarizes current literature on the migration of monomeric and polymeric PVC plasticizers from medical materials, food packaging, and toys. Especially highlighted is macromolecular engineering as a tool to increase the plasticizing efficiency and migration resistance for polymeric plasticizers.

Study of the migration of PVC plasticizers - ScienceDirect
Migration process may depend on the polymer properties (i.e. molecular weight), the nature and amount of the plasticizer, the plasticization process and the homogeneity of the compound and the surrounding media, i.e. nature, compatibility with the plasticizer, and effect on polymer, and obviously on the temperature, contact area and other
Migration of Monomeric and Polymeric PVC Plasticizers
Migration of Monomeric and Polymeric PVC Plasticizers 161 there have been many studies on the possible negative effects of some of the phthalates on human health and on the environment. In 2005, how-ever, the phthalates still constituted almost 90% of the world’s plasticizer market [2]. Because of the low molecular weight and the lack of chemical
- Can macromolecular engineering improve the migration resistance of polymeric plasticizers?
- This paper summarizes current literature on the migration of monomeric and polymeric PVC plasticizers from medical materials, food packaging, and toys. Especially highlighted is macromolecular engineering as a tool to increase the plasticizing efficiency and migration resistance for polymeric plasticizers.
- 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 better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
- Does PVC film affect specific migration of plasticizers into aqueous acidic foods simulant?
- The samples of commercial PVC film displayed lower values of specific migration of plasticizers into aqueous acidic foods simulant than the quantification limit (LOQ) of the respective methods, even with concentration of approx. 40% in the formulation of the film ( Table 9 ).
- What makes a polymeric plasticizer a more migration-resistant plasticizer?
- A more migration-resistant polymeric plasticizer that also better preserved its material properties during aging was obtained by combining a low degree of branching, hydrolysis-protecting end-groups, and higher molecular weight.

- Do plasticizers migrate into acidic foodstuffs?
- Thus, it has been demonstrated that a contact for prolonged time up to 40 °C did not promote the migration of plasticizers into acidic foodstuffs, but the migration of plasticizers to fatty foods can be high (75%–90% loss of plasticizers) and limit the use of PVC films as fatty food packaging. 1.
