Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887
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? - FineWoodworking
Start with a very fine compound. Long strokes, back and forth, with the grain, on the entire top. Mist with a little water from a spray bottle helps. Back and forth 2 or 3 times. Wipe it off and see how it looks.--That would be my first approach. It will bring out more shine than originally there, but the damage will hopefully disappear.
Study of the migration of PVC plasticizers - ScienceDirect
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
How common is the issue of plasticizer migration? : furniture
That’s in addition to the other issues, like the stain color coming off from all the edges of the desk. Is that normal for a wooden desk - it’s quite a bit of hassle to make sure nothing is touching the non glass part of the desk or it’ll be stuck to the wood the next day... Is that just a fault of the type of finish Macy used on the desk?

- 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.
- How does surface modification prevent plasticiser migration?
- In addition, surface modifications, such as surface coatings and crosslinking, are commonly employed to suppress plasticiser migration. 1, 72, 73 The modified surface layer acts as a barrier to the plasticiser and isolates the plasticiser from the exposed medium, preventing its migration. 1, 74
- What causes plasticiser migration in biopolymers?
- Studies have shown that the migration behaviour of plasticiser in biopolymers is often complex. This is caused by: (i) cold crystallisation during service/ageing, (ii) phase separation between the plasticiser and the polymer, and (iii) hydrolysis and interactions with water.
- How does temperature affect the plasticiser migration process?
- In addition, other ageing processes, such as the oxidation and annealing of polymers, are also accelerated at high temperature. 50 Any effects of these processes on the plasticiser migration process should be determined to yield a correct prediction.
- How do plasticisers leave a polymer?
- Plasticisers, when not chemically attached to polymer chains, can in certain conditions leave the polymer through migration, evaporation or extraction by liquids.
