Methods for determination of plasticizer migration from polyvinyl
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

Wheat bran addition as potential alternative to control the plasticizer
The migration process of three different biobased and biodegradable plasticizers [Triacetin (TA), acetyl tri- n -butyl citrate (ATBC) and oligomeric lactic acid (OLA)] was investigated adding them at a fixed amount of 10 wt.%. TA revealed the greater mass loss over the time as confirmed from the calculation of the diffusion coefficients.
Synthetical modification of plant oil‐based plasticizer with CO2 leads
Here, the migration of the plasticizer from the plasticized NBR sample to unplasticized NBR sample during short-term thermal aging was investigated using infrared spectroscopy (FTIR). Various techniques were adopted by different research groups to investigate the migration behavior of a plasticizer from polymer matrix.
Synthetical modification of plant oil-based plasticizer with CO 2
The increasing environmental and toxic health concerns due to phthalate-based plasticizers are pushing researchers to eliminate these market leader plasticizers and to find nature-friendly...
- What happens if a plasticizer migrates?
- Serious migration may result in substantial loss of plasticizer with resultant stiffening of the PVC. An example of plasticizer migration is softening of nitrocellulose or acrylic lacquer following prolonged contact with plasticized PVC.
- What is an example of plasticizer migration?
- An example of plasticizer migration is softening of nitrocellulose or acrylic lacquer following prolonged contact with plasticized PVC. In plasticized PVC film used for tape application, plasticizer migration to the adhesive layer can cause softening and loss of adhesion. 2017, Handbook of Plasticizers (Third Edition) GEORGE WYPYCH, ...
- 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.
- Do plasticizers migrate from plasticized PVC to other polymers?
- Plasticizers may migrate from plasticized PVC by contact to other polymeric substances if the resistance at the interface is low and if the plasticizer is compatible with the second polymer. Mobility, ease of diffusion, efficiency of the plasticizer, and temperature help determine the magnitude of the effects.
- Do plasticisers migrate from polymers to a gas phase?
- 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 temperature conditions and during accelerated ageing and testing.
- Do plasticizers affect film migration?
- As the total concentration of plasticizers is similar for all films ( Table 2 ), the combination of plasticizers influenced the migration of films (overall migration of 19.3 mg/dm 2, was determined for film 6, up to an overall migration of 50.4 mg/dm 2 for film 1).
