Plasma treatment reduces migration of plasticizers from blood bags
For Neubert, plasma treatment with atmospheric pressure is the instrument of choice, as it is considerably more economical than coating processes, which could also prevent plasticizer migration. “Coating processes must meet high demands. Coatings must ad-here extremely well and be flexible.
Plasma treatment reduces migration of plasticizers from blood bags
Plasma treatment reduces migration of plasticizers from blood bags . Medical products such as blood bags and tubing are often made from soft PVC, a plastic that contains phthalate plasticizers, which are suspected to be harmful nces are not chemically bound to the polymer, which means they can leach into the blood bags and thus come into contact

These substances are not chemically bound to the polymer, which means they can leach into the blood
Plasma treatment decreases movement of plasticizers from blood bags
95 percent barrier effect 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...
- Why is plasticizer migration a threat to human health?
- Since the 1970s, scientists had discovered the DEHP would migrate to the blood from PVC blood bags, which caused blood contamination and potentially harmful to human health [, , , ]. Potential security issues caused by plasticizer migration have aroused widespread attention.
- How does plasma technology improve PVC surface permeability?
- Biomolecular binding onto PVC substrate with the plasma technology is showed in Fig. 12. PVC surfaces treated with plasma can induce crosslinking reactions, which further facilitate the PVC surfaces and improve migration resistance of plasticizer [, , , , , , , ].
- Can irradiated PVC reduce plasticizer migration by network formation?
- Hypothesis of irradiated, crosslinked, and plasticized PVC can reduce plasticizer migration by network formation, which is presented in Fig. 13. Azidation reactions are shown in Fig..14, which is practical for the surface derivatization of commercial PVC tubing .
- 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].
- How does internal plasticization work?
- Internal plasticization strategies Internal plasticization is effective to prevent plasticizers migration and make PVC flexible via increasing distance and decreasing interaction force of main chains, then to promote PVC chains to move. Internal plasticizers with flexible branched chains and polar groups are grafted onto PVC chains.
- Can UV irradiation reduce the loss of plasticizer?
- There are two strategy to modify PVC surface via ultraviolet irradiation to prevent the loss of plasticizer. One is to induce a surface crosslinking by UV irradiation directly [126, 127]. Haishima et al investigated the property of PVC sheets treated with UV irradiation on their surfaces to suppress the elution of DEHP.
