Plasma treatment reduces migration of plasticizers from blood
The researchers’ tests showed that plasticizer migration from soft PVC could be reduced by 95 percent. To determine the barrier effect, the treated PVC films are stored in n-decane, a solvent, for two hours to identify the quantity of migrated plasticizers. To test the long-term stability of the barriers, the treated soft PVC films were
REDUCING THE MIGRATION OF PVC PLASTICIZERS - Fraunhofer
It was demonstrated at the Fraunhofer IST that the migration of plasticizers from plasticized PVC can be reduced by 95 percent by treatment in pure argon plasma (see Figure 2). Current knowledge attributes this effect to the plastic being Many medical products such as blood bags or flexible tubes are made of polyvinyl chloride (PVC). This
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was...

Study of the migration of PVC plasticizers - ScienceDirect
The PVC resin was dispersed into the plasticizer and the thermal stabilizer in a high-speed mixer in the following proportions: 55.3% of PVC, 41.4% of plasticizer and 3.3% of the thermal stabilizer; mixing operation was carried out under vacuum in order to avoid the presence of air bubbles in the final product.
- How to reduce migration of plasticizers out of polyvinyl chloride (PVC)?
- In order to reduce migration of plasticizers out of polyvinyl chloride (PVC), several techniques were attempted. First, binary blends of plasticizers were
- 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.
- 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 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.
- Why do plasticizers have a high migration resistance?
- A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance. As expected, the migration resistance was significantly higher than in films plasticized by DEHP because of the higher molecular weight of alkyl-HPGs .
- 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.
