Phthalates and alternative plasticizers and potential
Ortho-phthalate esters (e.g., di(2-ethylhexyl) phthalate, DEHP) are used as plasticizers to impart flexibility to polyvinyl chloride (PVC). These chemicals are widely used in PVC-based consumer
Methods for determination of 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.
Study of the migration of PVC plasticizers - ScienceDirect
Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer thermobalance, by heating the sample from 25 to 600 °C at 10 °C/min under a 20 ml (STP)/min flow of nitrogen. 3. Results and discussion Thermogravimetric study of different polystyrene samples reveals marked differences in the degradation process.
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer widely used in large applications due to the excellent balance between cost and properties. Due to the environmental and human health concerns of consumption of petrochemical-based plasticizers, the use of bio-based plasticizers has been increasing. The new blends of PVC made with green
Methods for determination of plasticizer migration
In this review, multiple methodologies developed over the last decade for determining plasticizer migration from PVC coating are compiled, with their operational principles, merits, and...
- 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 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.
- 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.
- Does plasticizer migrate from PVC?
- Kim et al. also found a similar trends for migration of plasticizer from PVC articles (Kim et al., 2022). Furthermore, the migration of low-molecular-weight PAEs (including DMP, DEP, DBP, and DIBP, with up to four carbon atoms in the chain) was significantly higher than that of high-molecular-weight PAEs (those with more than four carbon atoms).
- 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.
- Do plasticizers migrate from PVC to distilled water?
- Nevertheless, plasticizer migration from PVC blends with only one plasticizer, including extraction in distilled water, exudation and volatility, was investigated, showing the highest volatility of PVC/CA (about three times higher than for PVC/DOTP) and comparable extraction in distilled water.
