Kinetics Study of the Migration of Bio-Based Plasticizers in Flexible PVC C. Mao, D. Chan Materials Science The migration of bio-based plasticizers from flexible PVC was investigated by a solid-contact method using sandwiched PS sheets under pressure. A first-order migration kinetic equation was used to… Expand PDF View 1 excerpt, cites background
Migration of plasticizers from poly(vinyl chloride) and
The objective of the present study was to develop a procedure to evaluate the migration potential of nine plastic additives in aqueous infusion bags (NaCl 0.9% and glucose 5%): five phthalates, one adipate, two alkylphenols, and benzophenone.
Migrability of PVC plasticizers from medical devices into a
Migrability of PVC plasticizers from medical devices into a simulant of infused solutions Medical devices (MD) for infusion and artificial nutrition are essentially made of plasticized PVC. The plasticizers in the PVC matrix can leach out into the infused solutions and may enter into contact with the patients.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Phthalate Plasticizers Applications Cost: Phthalates which have been used as PVC plasticizers since the earliest days of flexible PVC are both inexpensive and effective. The collapse of oil prices which began in 2015 has further reduced the price of petrochemicals, including phthalate esters.
Small molecule plasticizers for improved migration resistance
The influence of branching on plasticizer effectiveness and migration behavior of heptyl-succinate plasticizers blended with poly (vinyl chloride) (PVC) was evaluated. An increase of...
- 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.
- Does plasticizer migration cause premature coating failure?
- Journal of Leather Science and Engineering 4, Article number: 8 (2022) Cite this article Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather.
- 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.
- Does PBA absorption affect plasticizer migration from flexible PVC?
- Integrating the profiles in terms of weight ratios, it is found that DEHP is adsorbed 300 % more than PBA, which justifies that gravimetry is insensitive towards PBA absorption. 4. Conclusions In this study, the plasticizer migration from flexible PVC in contact with rigid PVC sheets was investigated.
- How can we measure plasticizer migration in coextruded PVC pipes?
- Technologically relevant for plasticizer migration studies in coextruded PVC pipes. This study introduces and validates an effective approach for monitoring the plasticizer amount and its concentration profile in polyvinyl chloride (PVC) formulations. The method combines gravimetric measurements with confocal Raman depth profiling analysis.
- Do flexible PVC films migrate to RPVC films?
- As described in the experimental section, migration tests were conducted following the UNI EN ISO 177 standard. Flexible PVC formulations were kept in contact with rPVC films, and the plasticizer migration was evaluated by monitoring the weight increase of the rPVC sheet over time.
