A potentially general approach to aliphatic ester-derived PVC
As sustainable alternatives, aliphatic ester-derived plasticizers feature low cytotoxicity, biodegradability, and renewability, but they can only partially replace DEHP in PVC formulations because they have a strong tendency to migrate.
Methods for determination of plasticizer migration
2 Test methods for plasticizer migration In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
Recent Attempts in the Design of Efficient PVC Plasticizers
This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer showing low cost and excellent general properties [ 1 ]. PVC is one of the six most commonly used plastics (PE, PP, PS, PVC, PET, and PUR) accounted for 80.2% of the overall demand [ 2 ]. Global polyvinylchloride (PVC) market size was estimated at over 38 million tons in 2015 and is likely to
Migration of plasticizers from poly(vinyl chloride) and
Migration of plasticizers from poly(vinyl chloride) and multilayer infusion bags using selective extraction and GC-MS Flexible poly(vinyl chloride) (PVC) is widely used in the pharmaceutical industry for the manufacture of medical devices (tubes, probes, bags, primary packaging, etc.).
- Can PVC plasticizers migrate to a polymer in contact with flexible PVC?
- The ability of different PVC plasticizers to migrate towards a polymer in contact with flexible PVC has been investigated. A procedure based on the monitoring of the plasticizer concentration by infrared spectroscopy has been employed.
- 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.
- Why is plasticizer migration a problem?
- The plasticizer migration from the plastic item to its surroundings may involve the appearance of problems, namely the modification of flexibility of the PVC and the contamination of the media in contact with PVC.
- Why is extraction and migration of PVC plasticizers important?
- Exudation under pressure. The study of the extraction and migration of PVC plasticizers is of great importance for different reasons. Extraction of the plasticizer can occur in PVC films in contact with food, in bags or pipes in contact with biological fluids, such as blood, or even when a child could chew a PVC toy.
- How PVC plasticizers are extracted?
- Volatilization from the PVC surface to the air. Extraction from PVC to a liquid in contact with it. Migration from PVC to a solid or semi-solid in contact with it. Exudation under pressure. The study of the extraction and migration of PVC plasticizers is of great importance for different reasons.
- Does plasticizer nature influence the uptake kinetics in coextruded PVC pipes?
- The uptake kinetics is strongly influenced by plasticizer nature and PVC state. 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.
