Study of the Migration of Stabilizer and Plasticizer from

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.

The PVC resin was dispersed into the plasticizer and the thermal stabilizer in a high-speed mixer in the following proportions: 55.3% of PVC, 41.4% of plasticizer and 3.3% of the thermal stabilizer; mixing operation was carried out under vacuum in order to avoid the presence of air bubbles in the final product.

Know your Plasticizers: A New Study on Plasticizer Migration

However, in addition to toxicity issues, plasticizers can migrate from PVC into adjacent non-PVC thermoplastics, causing stability problems. 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, including connectors.

The study of the pyrolysis behaviour can be used in order to evaluate the amount of plasticizer migrated. Several samples must be analysed in order to obtain reliable results. The behaviour of plasticizers of different chemical families (i.e. phthalates and citrates) and molecular weights, has been studied.

Migration of phthalate and non‐phthalate plasticizers out of

The aim of the present work is to provide information about the migration of phthalate and non-phthalate plasticizers generally used in flexible polyvinyl chloride (PVC) applications. Plastisols (pastes) were prepared by mixing PVC, plasticizer, and thermal stabilizer. The plasticized PVC (p-PVC) films are obtained by gelation at 160°C for 15 min.

Migration of conventional and new plasticizers from PVC films

AGM plasticizers displayed higher coefficients of apparent partition than the other plasticizers under study. This difference in migration has been attributed to the different molecular structures of plasti-cizers. In addition, commercial films have been evaluated as to plasticizers concentration and specific migration into food simulants.

Recent Attempts in the Design of Efficient PVC Plasticizers

Unfortunately, the study on the migration of pure polymeric plasticizers from plastics was not performed. In 2017, Wang et al. [ 57 ] developed a new plasticizer containing hydroxyl and nitrogen groups, synthesized by a reaction of melamine and formaldehyde, followed by a reaction with tung-maleic anhydride and then with epichlorohydrin.

Migration of plasticizers from the gaskets of lids into oily

Specific migration of plasticizers. Migration can be related to the content of the plasticizer in the gasket, for example by calculating the migration in terms of mg/dm 2 for a concentration in the gasket of, for example, 10 %. This classifies plasticizers by their tendency to be transferred into food (specific migration).
