Migration of stabilizers and plasticizer from recycled
The migration of lead, cadmium, and zinc stabilizers from recycled unplasticized and plasticized polyvinylchloride (PVC) into deionized water (DW), saliva (SAS), and sweat (SWS) simulants was
Migration of stabilizers and plasticizer from recycled
Migration of the plasticizer diethylhexyl phthalate (DEHP) from plasticized PVC samples into the same liquids was also investigated. The results obtained indicate that these migration processes are mainly controlled and limited by the low solubility of DEHP in these liquids. No enhanced DEHP migration into SWS was observed. J.

Migration of stabilizers and plasticizer from recycled
Journal of Vinyl and Additive Technology The migration of lead, cadmium, and zinc stabilizers from recycled unplasticized and plasticized polyvinylchloride (PVC) into deionized water (DW), saliva (SAS), and sweat (SWS) simulants was investigated.
Methods for determination of plasticizer migration
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. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those

- How do plasticizers migrate from PVC synthetic materials?
- In general, plasticizer migration from PVC synthetic materials can proceed via three diferent mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- Do plasticizers migrate from MPVC to poly(dimethylsiloxane) via skin?
- There is a potential risk of exposure to PAEs from household PVC articles via skin. In the present study, the migration of plasticizers from modeled and commercial polyvinyl chloride (mPVC and cPVC, respectively) to poly (dimethylsiloxane) via artificial sebum was assessed to mimic the dermal migration of plasticizers.
- Are plasticizers and stabilizers changing in the PVC industry?
- For example, PVC plastics have been notorious for their extensive use of multiple hazardous ortho -phthalates as plasticizers and cadmium, lead, and tin as stabilizers. Consequently, the use patterns of plasticizers and stabilizers are changing in the PVC industry, shifting from well-known hazardous substances to alternative ones. (11,12)
- Do plasticizers migrate from polyvinylchloride infusion systems to lipid emulsions?
- Plasticizers migrate from polyvinylchloride (PVC) infusion systems into lipid emulsions. The aim of this study was to investigate the leaching of different plasticizers from PVC perfusion lines by a selection of lipid emulsions under clin. conditions.
- How do PVC plastics migrate Paes?
- Dermal migration of PAEs from PVC plastics via artificial sebum is assessed. Diffusion and migration are increased with sebum mass and temperature, while decreased with pressure and molar mass of PAE. Diffusion of DINP in soft PVC (cPVC) is higher than hard PVC (mPVC) sample tested.
- Do polymeric plasticizers migrate?
- The related researches on polymeric plasticizer and macromolecule plasticizers mainly focus on molecular structure design and migration in different solvents [, , ]. It is effective to prevent plasticizers migration via introducing branched chains and polar groups in their chemical structure [78, 79].
