Plasticizer Migration - an overview | ScienceDirect Topics
Plasticizer migration from one material to another causes problems with their performance.1,4 Figure 10.65 shows that plasticizer migration increases with the increase in the plasticizer concentration in PVC. The migration process follows Fickian diffusion and can be approximated from the following equation: Sign in to download full-size image
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
Study of the migration of PVC plasticizers - ScienceDirect
Migration test. Small squared strips of polystyrene ( 3 mm ×3 mm) with approximately 1 mm of thickness were placed between two PVC sheets of 2 mm of thickness, and kept under mild pressure (217 kPa) in a oven at 50 °C for 1 week. Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer
Common Signs Of Plasticizer Migration - Chaffee Industrial
The plasticizer, which makes PVC a flexible membrane, will react with residue from an older installation, causing it to leak. The migration weakens the bond causing it to crack or split and causes the PVC to lift around the edges. Regular inspections will help you spot this problem before it causes trouble. Check for brittleness
Know your Plasticizers: A New Study on Plasticizer Migration
In such applications, according to the study, certain plasticizers can cause softening, cracking, or other defects in the non-PVC components as they migrate across the interface between the PVC and the connecting material. In contrast, other plasticizers exhibit little or no effect.
- 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 do we detect plasticizer migration from PVC synthetic materials?
- To this end, this review is compiled as a general review of the methods now available for detecting plasticizer migration from PVC synthetic materials via three different mechanisms (i.e., volatilization, exudation, and extraction), with an emphasis on the instrumentation, methodology, advantages, and limitations of each method.
- Can plasticizers migrate from flexible PVC parts to other media?
- An accelerated method has been set up in order to study the capacity of migration of different commercial plasticizers from flexible PVC parts towards other media kept in contact with it; in this case, polystyrene (PS) has been used as example.
- Does plasticizer migration cause premature coating failure?
- Journal of Leather Science and Engineering 4, Article number: 8 (2022) Cite this article 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.
- 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.
