Plasticiser loss from plastic or rubber products through
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
What is Plasticizer Migration? - Flooristics
What is plasticizer migration? It’s when the plasticizer chemicals within vinyl, plastic or rubber migrates out and is absorbed by surrounding materials. For example, a rubber mat placed on a bathroom floor covered with vinyl may eventually leave a yellowish stain where the mat made contact with the vinyl.
Plasticizer Migration: What Is It? - Flooristics
Plasticizer is a chemical combination that is added to vinyl, rubber and plastic material during the manufacturing phase that makes it more flexible. If the piece is quite soft, there is a lot of plasticizer in it. Over time, the plasticizer breaks down and migrates out of the rubber.
Plasticizer Migration: What is it and why is it a problem
Plasticizer migration is the unwanted net movement of a plasticizer component out of a compound (like an adhesive or plastic). It can occur through gas volatilisation, liquid extraction, or solid migration. Collectively these are known as plasticizer migration. Plasticizers are often put into materials to make them more flexible or malleable.
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
- What is plasticizer migration?
- Plasticizer migration refers to the process when plasticizer chemicals within vinyl, plastic or rubber migrate out and are absorbed by surrounding materials. For example, a rubber mat may leave a yellowish stain where it made contact with a vinyl floor due to plasticizer migration.
- Does plasticizer migration affect adhesive performance?
- Plasticizer migration can cause other additives to migrate too. Typical examples of these additives are UV stabilisers or Anti-Oxidants. If plasticizer migration causes these additives to migrate, the overall performance of the adhesive will deteriorate. There are several occasions where plasticizer migration can have aesthetic effects.
- 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.
- Can plasticizer migration cause flooring failures?
- Photo: Gary Sheidker. 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.
- What is plasticizer migration out of sheet vinyl?
- Plasticizer migration out of sheet vinyl is something that is all too common in the flooring industry. The consequence of plasticizer migration is a range of floor compatibility issues and that can lead to both short-term and long-term problems.
- What is the best floor sealant for plasticizer migration?
- To prevent plasticizer migration, it's recommended to use a non-reactive floor sealant that neutralizes the chemical reaction causing the migration. Alternatively, you can choose products with non-reactive backing materials.
