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
Plasticizer Migration Causes What Problems in Sheet Vinyl?
Plasticizer migration occurs when adhesive, new or leftover, creates a chemical reaction with the PVC in the new sheet vinyl. Plasticizer is a key part of the vinyl that keeps it from being brittle. When plasticizer migration happens, sheet vinyl can soften, discolor, loosen, crack or turn brittle.
Plasticizer Migration: What is it and why is it a problem
Migration of plasticizers through these other components to the surface of a plastic under stress is a likely culprit to blame for environmental stress cracking. So in the right conditions, plasticizer migration can cause environmental stress cracking to take place. Plasticizer migration can impact a products performance
What is Plasticizer Migration? - Flooristics
Plasticizer migration can happen over time, but pressure and heat can speed up the migration. The best way to avoid this chemical reaction in sheet vinyl is to thoroughly prime and seal the sub flooring. It’s also a good idea to use a non-reactive floor sealant that will neutralize any kind of plasticizer migration.
Plasticizer Migration - an overview | ScienceDirect Topics
Migration rate of plasticizer increases when interaction between polymer and plasticizer decreases. Also increase in the polyethylene crystallinity degree decreases the migration of plasticizer from external source because sorption and diffusion processes in polymers mainly occur in the amorphous phase.
- What happens when plasticizer migrates to sheet vinyl?
- When plasticizer migration happens, sheet vinyl can soften, discolor, loosen, crack or turn brittle. The best way to avoid this in sheet vinyl is to prime and seal the sub floor. There are many non-reactive floor sealants available that can minimize the effects of a reaction and cover up old adhesive that may trigger them as well.
- 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 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.
- How do you prevent plasticizer migration in sheet vinyl flooring?
- To prevent plasticizer migration in sheet vinyl flooring, it's recommended to thoroughly prime and seal the sub flooring. Using a non-reactive floor sealant is also a good idea, as it will neutralize any kind of plasticizer migration. Plasticizer migration can occur over time, but pressure and heat can speed up the process.
- 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.
- Why does vinyl flooring have a high plasticizer content?
- A general rule is the more flexible the vinyl flooring is, the higher the plasticizer content. 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.
