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.
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.
Synthesis of a new polyurethane-based liner modified by
The aim of this work is the study of the reduction of dioctylphthalate (DOP) plasticizer migration from polyurethane (PU) to ethylene propylene diene monomer (EPDM) substrate by using a polyurethane-based liner containing carboxylated carbon nanotube (CNT). Dispersion of CNT in PU was well performed using DMAc solvent and sonication. Dispersion rate was evaluated by FESEM analysis. In order to
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
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer showing low cost and excellent general properties [ 1 ]. PVC is one of the six most commonly used plastics (PE, PP, PS, PVC, PET, and PUR) accounted for 80.2% of the overall demand [ 2 ]. Global polyvinylchloride (PVC) market size was estimated at over 38 million tons in 2015 and is likely to
- 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 plasticizers migrate from plasticized PVC to other polymers?
- Plasticizers may migrate from plasticized PVC by contact to other polymeric substances if the resistance at the interface is low and if the plasticizer is compatible with the second polymer. Mobility, ease of diffusion, efficiency of the plasticizer, and temperature help determine the magnitude of the effects.
- Why is plasticizer migration important?
- 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-eficient simulant of genuine leather.
- Do plasticizers have migration resistance?
- Therefore, any emerging plasticizer that succeeds in this arena of inten-sive competition is required to demonstrate excellent migration resistance, a crucial indicator governing how the resulting PVC coating holds up against long-term service and low environmental impact [9, 10].
- What is an example of plasticizer migration?
- An example of plasticizer migration is softening of nitrocellulose or acrylic lacquer following prolonged contact with plasticized PVC. In plasticized PVC film used for tape application, plasticizer migration to the adhesive layer can cause softening and loss of adhesion. 2017, Handbook of Plasticizers (Third Edition) GEORGE WYPYCH, ...
- Does a high Tc content affect the migration of plasticizer?
- The activation energy is obviously reduced with the increasing TC content as demonstrated by Zhang and Sun , which further confirms that a high plasticizer content makes migration much easier than low content. Migration of plasticizer is also affected by the molecular size of the plasticizer.
