Wheat bran addition as potential alternative to control the
However, despite of its composition rich in polysaccharides (cellulose, hemi-cellulose and starch), the WB filler ability to control the plasticizer migration has not been yet investigated. In this study, the addition of different wheat bran (WB) amounts was investigated to control the plasticizer migration of PLA/PBSA plasticized binary blends.
How common is the issue of plasticizer migration? : furniture
How common is the issue of plasticizer migration? So, I bought a desk from Macy’s a couple of years back. After a year or so, I noticed a phenomenon: almost everything that touches the desk gets “melted into the finish”. The most notable culprit is eraser shavings, which seem to “melt” into the finish in a day or so.
repair advice needed about wood table damaged by plastic cover
What you are probably seeing is a phenomenon called "plasticizer migration." The way I explain it is that the chemicals in the plastic to keep it soft and flexible migrate into the finish and do the same there. There is no saving the damaged finish, it must be removed. What repair is needed depends upon the extent of damage.
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

In order to make plastics and lacquers, which are a type of plastic, more flexible (that is, less brittle), plasticizers, which are a type of oil, are added. When plastics are placed on a lacquer surface, especially under some weight, they can stick to the lacquer and sometimes cause it to turn white.
- What is plasticizer migration?
- 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.
- 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.
- Do polymeric plasticizers migrate?
- The related researches on polymeric plasticizer and macromolecule plasticizers mainly focus on molecular structure design and migration in different solvents [, , ]. It is effective to prevent plasticizers migration via introducing branched chains and polar groups in their chemical structure [78, 79].
- 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.
- Why do plasticizers migrate from PVC to adhesives?
- 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 is more likely to happen in certain circumstances.
- What is the loss of plasticizer?
- The loss of plasticizer includes gas volatilization, liquid extraction and solid migration according to the difference of the external medium. In order to express convenience, the loss of plasticizer in the three ways is collectively referred to as migration. Plasticizer migration has been discovered and concerned for half a century.
