The plasticizer can migrate from PVC-based devices and storage bags into physiological fluids, however, and has been detected in storage media such as blood, plasma, serum, drug solutions and fatty foods, as well as in the bodies of patients undergoing haemodialysis and transfusion.

Eastman Plasticizers for PVC
Eastman 168 non-phthalate plasticizer has been safely used in PVC for generations. With proven performance as an alternative to DOP/DEHP and DINP, Eastman 168 can be used for a wide variety of flexible PVC applications. In many cases, our non-phthalate solutions can be a drop-in replacement for traditional phthalates in your manufacturing
- Can plasticizers migrate from flexible PVC parts to other media?
- An accelerated method has been set up in order to study the capacity of migration of different commercial plasticizers from flexible PVC parts towards other media kept in contact with it; in this case, polystyrene (PS) has been used as example.
- 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.
- What is a plasticizer in PVC?
- Introduction Plasticizers are additives that can improve the flexibility and workability of poly (vinyl chloride) (PVC) by forming secondary bonds (dipole–dipole interactions) with the polymer chains. The high density of the ends of the plasticizer chains introduces additional free volume into the PVC matrix .
- Can PVC be plasticized?
- PVC can be plasticized with varying amounts of plasticizers to form flexible PVC. Phthalate plasticizers, such as di-isononyl phthalate (DINP) and di- (2-ethylhexyl) phthalate (DEHP), are common plasticizers that are widely used in industrial applications .
- Which plasticizers are used in flexible PVC?
- In flexible PVC formulations, esters derived from phthalic acid are the most common monomeric plasticizers, although other compounds based on various organic acids (phosphates, trimellitates, citrates, sebacates, and adipates) can also be used [6, 7].
- What are flexible PVC (pPVC) formulations?
- Several flexible PVC (pPVC) formulations were compared in this study, including: pPVC@DEHP, using the monomeric plasticizer di (2-ethylhexyl) phthalate (DEHP); pPVC@PBA, using the polymeric plasticizer poly (butylene adipate) (PBA); and crosslinked pPVC (cPVC@DEHP), where isophorone diamine (IPDA) served as the crosslinker.
