A Strategy for Nonmigrating Highly Plasticized PVC - Nature
The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed. Unlike other reported methods, this approach increases the interaction between...
Plasticiser loss from plastic or rubber products through
This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service...
Prevention of plasticizer migration from PVC products
Such crosslinking provides a thin coating which prevents leakage of plasticizer and additives from the plasticized PVC substrate when it is contacted with solvents. Preferred modification of...
Methods for determination of plasticizer migration
Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those
REDUCING THE MIGRATION OF PVC PLASTICIZERS - Fraunhofer
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 material is inexpensive, transparent, weldable and has low-temperature flexibility. To obtain the flexibility up to 40 wt.% of plasticizer has to be added to the material.
- Do Plasticizers improve the migration resistance of plasticized PVC material?
- This indicates that a moderate increase in the relative molecular weight of the plasticizer can effectively improve the migration resistance of the plasticized PVC material, a finding consistent with the results from the resistance tests. There has been no clear evidence observed regarding the plasticization process of plasticizers in PVC.
- Do plasticizers migrate?
- To observe the migration of plasticizers, the migration behaviour of the new DOP-like plasticizer in PVC was tested through extraction experiments with n-heptane at room temperature 35. As a comparison, migration of DOP was also measured under the same conditions.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- 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.
- How can we measure plasticizer migration in coextruded PVC pipes?
- Technologically relevant for plasticizer migration studies in coextruded PVC pipes. This study introduces and validates an effective approach for monitoring the plasticizer amount and its concentration profile in polyvinyl chloride (PVC) formulations. The method combines gravimetric measurements with confocal Raman depth profiling analysis.
- 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.
