Plasticiser loss from plastic or rubber products through diffusion and
Royaux et al. 40 reported that at 80 °C, the plasticiser migration from PVC transitioned from a diffusion-controlled mode in an open air environment to an evaporation-controlled mode in a...
Plasticizer leaching from flexible PVC in low temperature caustic
For the recycling of PVC and plasticizer, a low-temperature treatment process for flexible PVC has been developed, using environmentally friendly caustic solution. Maintaining low temperature during the processing prevents dechlorination of the PVC, which allows the recycle of the PVC and plasticizer.
Plasticizer leaching from flexible PVC in low temperature caustic
By separating plasticizer using alkali solution at low temperature, the recycling of PVC and plasticizer is possible. A low temperature leaching process has been developed and the...
A Strategy for Nonmigrating Highly Plasticized PVC
Unfortunately, although the modified PVC came from a common plasticizer DOP, it had very poor plasticization performance and its glass transition temperature cannot fall below 20 °C without a...
Prevention of plasticizer leaching from PVC medical devices by using
Unfortunately, CVD often suffers from high coating temperatures, which makes it impossible to coat temperature-sensitive materials like polymers. Recently, a plasma-assisted CVD process was developed to coat PVC at very low temperatures with titanium-based layers [10], which seems to have the potential to prevent leaching of plasticizers from PVC.
- 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.
- Can a low temperature alkali treatment process be used for plasticizer separation?
- In this study, a low temperature alkali treatment process for plasticizer separation is developed and its performance is investigated. Because dechlorination of flexible PVC material is difficult at low temperatures, a low temperature process to separate the plasticizer without the dechlorination is employed here. 2. Experimental 2.1.

- Are flexible poly (vinyl chloride) phthalate based plasticizers toxic?
- Uses of flexible poly (vinyl chloride) (PVC) are restricted by plasticizer migration affecting material properties. Moreover, the use of phthalate-based plasticizers is being questioned worldwide because of their potential toxicity to humans and environment.
- What is the energy gain of plasticizer leaching?
- If we assume that half of the solvation layer is recovered during the migration into bulk solution, the plasticizer leaching allows an energetic gain between -44 and -33 kJ mol −1 in water and between -59 and -49 kJ mol −1 in ethanol. In the water-ethanol mixture, the gain ranges from -64 to -47 kJ mol −1. Fig. 6.
