Study of the Migration of Stabilizer and Plasticizer
Abstract. This study investigates the determination and migration of stabilizers and plasticizers from polyethylene terephthalate (PET). Two methods [ultrasonic extraction with dichloromethane or methanol and total dissolution with phenol/tetrachloroethane (m:m/1:1)] for pre-concentration of additives in PET material were performed.

This study investigates the determination and migration of stabilizers and plasticizers from polyethylene terephthalate (PET). Two methods [ultrasonic extraction with dichloromethane or methanol and total dissolution with phenol/tetrachloroethane (m:m/1:1)] for pre-concentration of additives in PET material were performed.
Effect of temperature and plasticizer content
Wang et al. (2018) investigated migration of five stabilizers from polypropylene (PP) film into 50 v / v % ethanol and isooctane food simulants at different temperatures. The migration of additives was simulated – based on experimental results – using molecular dynamics simulation technique.

Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer thermobalance, by heating the sample from 25 to 600 °C at 10 °C/min under a 20 ml (STP)/min flow of nitrogen. 3. Results and discussion Thermogravimetric study of different polystyrene samples reveals marked differences in the degradation process.

- What is the migration kinetic mechanism of plastic stabilizers?
- At high contact temperature (40 °C for PLA and 60 °C for PP), the migration kinetic mechanism of stabilizers from plastics with no plasticizer content is very similar to that of plastics with 10 w % TBAC at low contact temperature (20 °C for PLA and 40 °C for PP). For example, BHT shows this behavior in case of both polymers.
- Does contact temperature and plasticizer content affect the migration of stabilizers?
- 4. Conclusion The effect of contact temperature and plasticizer content of PLA and PP on the migration of commonly used stabilizers (BHT and Irgafos 168 – antioxidants and Uvinul 3039 and Tinuvin 900 – UV absorbers) were investigated in 13-days long experiments.
- Does temperature affect the migration of stabilizers from plasticized PLA and PP?
- Migration of stabilizers from plasticized PLA and PP was studied. The migration rate of stabilizers increases with tributyl acetyl citrate content. Cluster analysis is a good tool to compare the kinetics of migration and swelling. Effect of elevated temperature on migration resembles that of plasticization.
- 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 increase migration?
- The increase of migration due to the plasticization effect of additives (especially plasticizers) can easily be comparable – both in extent and mechanism – with the promoting effect of increased contact temperature.
- Why do plasticizers migrate from propellant to liner?
- The migration phenomenon occurs mainly due to the differential concentration of plasticizers and stabilizer between the additive part and the nonadditive part. All these components were added in propellant originally, and none was in liner, neither was in insulation, so they migrated from propellant to liner and insulation.
