Impact of alternative materials to plasticized PVC infusion
The aim of this study was to assess interactions between drugs and five alternative materials to a reference plasticized PVC intravenous (IV) infusion tubing: three were PVC coextruded with polyethylene (PE), polyurethane (PU) or a thermoplastic elastomer (Styrene-EthyleneButadiene-Styrene (SEBS)) and two were SEBS or thermoplastic olefin (TPO
Bioplastic may replace plasticizers in PVC IV tubing
New biobased PHA (polyhydroxyalkanoate) copolymers can replace plasticizers in polyvinyl chloride (PVC), potentially enhancing its acceptability in the medical market. Metabolix (Cambridge, MA) says it has demonstrated that a series of PHA copolymers miscible with PVC resins improved various physical properties.

The prices of bioplastics and fossil-based plastics 8,66,118 are compared in Table 1, showing that current bioplastic premiums can be ~50% (bioPE) but also 3–4 times more expensive (PHAs) than
PVC infusion tubing drug sorption and plasticizer release
The aim of this study was to assess interactions between drugs and five alternative materials to a reference plasticized PVC intravenous (IV) infusion tubing: three were PVC coextruded with polyethylene (PE), polyurethane (PU) or a thermoplastic elastomer (Styrene-EthyleneButadiene-Styrene (SEBS)) and two were SEBS or thermoplastic olefin (TPO)
IV Sets tubing materials - BD
DEHP is a chemical commonly used in PVC tubing; used to yield clarity and soft pliable tubing. IV sets that DO NOT contain DEHP are identified in our IV sets and accessories catalog as “DEHP-free.” Select sets are identified as low sorbing. These sets are polyethylene lined, (inert internal surface), with a PVC-free fluid path.
- Are plasticizers compatible with PVC?
- By analyzing the relationship between molecular structure and performance of plasticizers, researchers found that the presence of carbon–carbon double bonds and hydroxyl groups reduces the compatibility of plasticizers with PVC, while the epoxy groups and ester bonds can improve the plasticizing capability of plasticizers on PVC.
- What is the interaction between bio-plasticizer and PVC?
- The interaction between the Bio-Plasticizer and PVC is facilitated by various mixing techniques, typically conducted at temperatures ranging from 25°C to 70°C, which ensures efficient dispersion and absorption of the plasticizer within the PVC particles.
- How are bio-plasticizers used in PVC?
- Bio-Plasticizers are integrated into polyvinyl chloride (PVC) during the manufacturing process to enhance the material’s flexibility and workability. This incorporation occurs through a process known as internal plasticization, where the Bio-Plasticizer interacts with the polymer matrix at a molecular level.
- Can phthalate plasticizers be substituted for bio-PVC?
- However, the use of renewable resources for production of green plasticizers for PVC represents a promising option to overcome the environmental problems caused by phthalate plasticizers. Potential substitution of PVC with bio-PVC or other biodegradable polymers should be taken into consideration.
- Does bio-based plasticizer modify PVC film?
- PVC modified with bio-based plasticizers showed excellent thermal properties, as well as low values of exudation test, migration, and volatility. Low migration of PVC film was exhibited at the bio-based plasticizer modified with epichlorhydrin .
- Do medical tubings in plasticized polyvinylchloride cause content-container interactions?
- Articles from Scientific Reports are provided here courtesy of Nature Publishing Group Medical tubings in plasticized polyvinylchloride (PVC) are widely used for the infusion of medications but are known in some cases to cause content-container interactions (drug sorption and plasticizer release). The aim of this study was to assess ...
