Plasticizer migration from cross-linked flexible PVC: Effects
Flexible formulations were held in contact for 32 days with rigid PVC sheets. Plasticizer migration towards the interface caused an increase of dynamic friction compared to that of the...
Plasticizer migration from crosslinked flexible PVC: Effects
Uses of exible poly(vinyl chloride) (PVC) are restricted by plasticizer migration affecting material properties. Moreover, the use of phthalate-based plasticizers is being questioned...
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
Plasticizer migration from cross-linked flexible PVC: Effects
In this work, a flexible dry blend based on cross-linked PVC was obtained using a difunctional amine, namely isophoron diamine (IPDA) as the cross-linking agent. The gel fraction was evaluated from insoluble portions obtained by means of solvent extraction; the efficiency of cross-linking in reducing the plasticizer leaching was evaluated by
- How to reduce plasticizer diffusion?
- Chemical modification of PVC structure is one of the most effective tools for reduction of plasticizer diffusion. In this work, a flexible dry blend based on cross-linked PVC was obtained using a difunctional amine, namely isophoron diamine (IPDA) as the cross-linking agent.
- What is the migration of plasticizer?
- Migration of the plasticizer ues by a whole order of magnitude. The migration of at the interface . values. Since only DOP after a long-term aging. cross-linking agent for PVC dry blends. The increase of rable cross-linking densities. ing the mechanical properties of flexible PVC.
- How plasticizer migration affecting material properties in construction industry?
- Construction industry alone by plasticizer migration affecting material properties. uses very large quantities of PVC annually and due to Moreover, the use of phthalate-based plasticizers is plasticization process rigid PVC is converted into the being questioned worldwide because of their potential toxicity to humans and environment.
- Does plasticizer migration affect cross-linker loading?
- caused by the plasticizer migration. Nevertheless, the turned out to be independent of the cross-linker loading. B2, and B3. This behavior was attributed to the compara- samples. TABLE 2. Weight percentage of gel and cross-linking density values for flexible PVC samples. FIG. 2. Migration tests. Weight change of rigid PVC sheets after being
- 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.
