The plasticizer absorption behavior of PVC: Journal
The Calm microbalance system for plasticizer absorption in PVC resin has been used to study the different absorption behaviors of two different plasticizer systems [diisodecyl phthalate (DidP) and a mixed system] on resins of various origins [50-gal reactor and the large reactor pilot plant (LRPP)] and polymerization conditions [different killing

Effect of Plasticizer Percentage on Thermal Properties
The effect of DOP plasticizer percentage on limiting oxygen index and thermal stability of plasticised PVC was investigated in this paper. DOP was added PVC with various quantities (20, 30,...
Natural-based plasticizers and biopolymer films: A review
The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- 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.
- 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.
- How to monitor plasticizer concentration profiles in coextruded PVC pipes?
- A spectroscopic approach to monitor concentration profiles in plasticized PVC. Cross-validation of the depth-profile analysis by gravimetric measurements. The uptake kinetics is strongly influenced by plasticizer nature and PVC state. Technologically relevant for plasticizer migration studies in coextruded PVC pipes.
- How does crosslinked PVC affect plasticizer uptake?
- Crosslinked PVC exhibits a more complex behaviour: an induction period is observed in this case. followed by a sudden increase of the plasticizer uptake, likely related to the gradual relaxation of the gelled regions. When the plasticizer is of polymeric nature, the migration process slows-down considerably and the total uptake lowers.
- Does flexible PVC reduce plasticizer leaching?
- In this study, the plasticizer migration from flexible PVC in contact with rigid PVC sheets was investigated. Various formulations of flexible PVC were compared, highlighting reduced plasticizer leaching when pPVC was chemically crosslinked or when the monomeric plasticizer, DEHP, was replaced with the polymeric plasticizer, PBA.
