The migration of DEHP is a critical issue due to its toxicity, particularly in the pharmaceutical industry, in medicine and in food packaging [9, 11]. Thus, studying plasticizer
plasticizers behave like solvents but they are not chemically bounded to PVC [19]. Figure 1 presents the plasticizers IR spectra, which are very much similar due to similarities of the structure. Figure 2 shows the characteristic bands of PVC, plasticizer, lubricant and CaCO 3. The presence of PVC is given by de C-Cl bond appearing around 600
- How to evaluate volatilization propensity of plasticizers from PVC synthetic materials?
- Currently, the most commonly employed methods that enable quantitative evaluation of the volatilization propensity of plasticizers from PVC synthetic materials are fogging test and activated carbon method.
- How to evaluate the exudation tendency of plasticizers from PVC coatings?
- Specimen arrangement as described in ISO 177:2016 (E) that evaluates the exudation tendency of plasticizers from PVC coatings into other materials when they are brought into close contact Theoretically, the loss in mass of the specimens should be equal to the increase in the mass of the absorbent backing discs.
- How to measure plasticizer exudation?
- Similar procedure that enables measurement of plasticizer exudation are also available in ASTM D2199-03 . In this method, a lacquer film is flattened on a glass panel, and covered by a PVC synthetic material specimen with the PVC coating surface being in close contact with the film.
- 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.
- How does plasticizer exudation work?
- 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.
- What is the most common plasticizer?
- DEHT, a structural isomer to DEHP, was the most common plasticizer and was detected in four of the six backpacks with mass content ranging from 5.38±1.98% to 25.5±3.54% and in six out of the seven plastic toys with mass content ranging from 8.17±1.85% to 21.2±1.11%.
