Study of the Migration of Stabilizer and Plasticizer
The specific migration data can be obtained from migration tests carried out under controlled conditions of time and temperature of contact between the materials and food simulants. Phthalate esters, light stabilizers based on benzotriazoles and antioxidants were reported to be used in the production of PET packaging (2, 3). Phthalate esters as
Ionic liquids: New generation stable plasticizers for poly
The traditional plasticizers, especially the phthalates, were more prone to migration when in contact with an unplasticized surface. Also the relative migration of the three traditional plasticizers matched the trend observed elsewhere [35]. The ILs, having distinct polar groups, were fairly compatible with the polar ends of PVC.
Phthalates in Food Packaging and Food Contact Applications
The FDA revoked authorizations for the food contact use of 23 phthalates and two other substances used as plasticizers, adhesives, defoaming agents, lubricants, resins, and slimicides.
Plasticiser loss in heritage collections: its prevalence
They can be present in high concentrations (up to 40%); therefore, migration of plasticisers can cause significant physical changes, such as embrittlement and dimensional changes. For this reason, plasticisers and particularly phthalates are the main target of this review.
Uses of Phthalates and Other Plasticizers - U.S. Consumer
Building wire Very safe for long term use, Low volatility, low conductivity, ease of processing Higher MW plasticizers such as DIDP, DPHP, trimellitates, L911P, L11P, DTDP Low MW phthalates including DEHP, citrates, Cyclohexanoates, natural oil based Wire and Cable- other Safety is always important.
- Do phthalate plasticizers have migration resistance?
- There are a lot of studies describing novel plasticizers that exhibit excellent migration resistance at the expense of the deterioration of mechanical properties. Since phthalate plasticizers have become a subject of legal restrictions in many countries, developing a robust plasticizer emerges as an urgent need.
- Do Plasticizers improve the migration resistance of plasticized PVC material?
- This indicates that a moderate increase in the relative molecular weight of the plasticizer can effectively improve the migration resistance of the plasticized PVC material, a finding consistent with the results from the resistance tests. There has been no clear evidence observed regarding the plasticization process of plasticizers in PVC.
- Are phthalate plasticizers safe?
- Despite their low cost and favorable performance, phthalate plasticizers exhibit high volatility and poor solvent resistance, making them susceptible to migration from PVC and raising significant safety concerns [9, 10, 11].
- 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.
- Which phthalate is used as a thermal stabilizer?
- The ASUA 656-T2, a calcium zinc stabilizer from Industrias Quı́micas Asua, was employed as thermal stabilizer. Plasticizer employed were the phthalates, diheptyl phthalate (DHP), DEHP and DINP, from BASF and the citrates, acetyl triethyl citrate (ATEC) and acetyl tributyl citrate (ATBC), from Chemical S.P.A. and acetyl trihexyl citrate (ATHC) from
- Does plasticizer improve the thermal stability of PVC?
- It is obvious that the addition of plasticizer significantly improves the thermal stability of PVC, which should be attributed to the good thermal stability of the ester group. PEE has a macromolecular structure, and the strong intermolecular interaction further improves its thermal stability, resulting in a better improvement effect than DOP.
