Common Signs Of Plasticizer Migration - Chaffee Industrial
When the plasticizer leaks from a PVC roof, it will cause cracks, splits, and welded sections to break apart. Combining plasticizer migration with foul weather means disaster for your roof. Early spotting of the common signs of plasticizer migration helps protect your roof. Let’s take a look at some of the telltale indicators.
Plasticiser loss from plastic or rubber products through
Plasticisers are commonly added to polymers to lower their glass transition temperature and increase their processability, mechanical flexibility, ductility and toughness. 1, 2, 3, 4, 5 They...
Plasticizer Migration: What is it and why is it a problem
Collectively these are known as plasticizer migration. Plasticizers are often put into materials to make them more flexible or malleable. As an example, PVC is heavily-plasticized to increase its flexibility. So when bonding PVC with adhesives, those plasticizers can migrate from the PVC into the adhesive.
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
Methods for determination of plasticizer migration
In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- What causes plasticizer migration?
- Plasticizer migration is a common cause of flooring failures. Plasticizers can come from the flooring, sound control underlayment, maintenance products and even some concrete substrates. These plasticizers can attack the polymers in some adhesives, causing them to degrade over time. Most resilient flooring products contain plasticizers.
- What are the three stages of plasticizer migration?
- There are three stages for the migration of plasticizer: (1) the plasticizer diffusion from the inside to the surface, (2) the plasticizer through the surface, (3) the plasticizer through the surface to the external medium .
- 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?
- There are several occasions where plasticizer migration can have aesthetic effects. Fogging in glass automotive applications – The plasticizer in an automotive dashboard application outgasses, causing the glass around it to fog up. Paint issues – Migrating plasticizers can damage the finish of the paint.
- Why is plasticizer migration a threat to human health?
- Since the 1970s, scientists had discovered the DEHP would migrate to the blood from PVC blood bags, which caused blood contamination and potentially harmful to human health [, , , ]. Potential security issues caused by plasticizer migration have aroused widespread attention.
- 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.
