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.
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 - an overview | ScienceDirect Topics
plasticizer migration to optical fiber coating may result in decreased coating adhesion and possible delamination5. leaching of plasticizer may cause degradation of properties of encapsulated fiber in telecommunication cable 14. when diisooctyl phthalate was used in telecommunication cable strip force was reduced by 90% after 6 months aging at
Common Signs Of Plasticizer Migration - Chaffee Industrial
If you have a PVC roof system, you need to know the common signs of plasticizer migration. A plasticizer is added to PVC during manufacturing to make the polymer flexible. Without the plasticizer, the PVC would be a solid material and impossible to work into place.
Study of the migration of PVC plasticizers - ScienceDirect
2.3. 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
- 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, ...
- Do plasticizers migrate better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
- 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 plasticizers migrate into acidic foodstuffs?
- Thus, it has been demonstrated that a contact for prolonged time up to 40 °C did not promote the migration of plasticizers into acidic foodstuffs, but the migration of plasticizers to fatty foods can be high (75%–90% loss of plasticizers) and limit the use of PVC films as fatty food packaging. 1. Introduction
- Do plasticizers migrate into food simulants?
- In addition, commercial films have been evaluated as to plasticizers concentration and specific migration into food simulants. It was found that 25% of the samples comply with the specific migration limits for fatty foods contact while 50% might be used for contact with fatty foods with FRF 2–5.
