Plasticizer Migration – Floor Detective
Plasticizer migration is a phenomenon caused by the slow release of “Free” plasticizers from PVC-backed modular carpet or vinyl products. Plasticizers are additives used to make plastics softer and more workable so they can be used in a variety of commercial applications.,how to remove plasticizer that is migrated to a pvc cover … ,Migration of PVC plasticizers into alcohols. 1/11/1975 · Migration of PVC plasticizers into alcohols Emmanuel M.,What is Plasticizer Migration? – Flooristics ,Another example is the plasticizer migrates down into the adhesive, which break it down and leave it ineffective. Plasticizer migration can happen over time, but pressure and heat can speed up the migration.
Know your Plasticizers: A New Study on Plasticizer Migration
However, in addition to toxicity issues, plasticizers can migrate from PVC into adjacent non-PVC thermoplastics, causing stability problems. To address this phenomenon, Teknor Apex (Pawtucket, RI) has published a study focusing on plasticizer migration, which can affect a range of medical device components, including connectors.,Migration of dioctylphthalate and dioctyladipate … ,The 4 E. Kondyli, P. G. Demertcis, M. G. Kontominas Fig. 1.

The combined ether extracts were left overnight with 30g of anhydrous sodium sulphate.,Studying DEHP migration in plasticized PVC used for blood … ,Plasticized PVC is widely used to make medical devices such as tubing, perfusion bags and blood bags. By using confocal Raman microscopy on a PVC sheet plasticized with around 40% of di-(2-ethylhexyl)phthalate (DEHP), we propose a simple and sensitive approach to studying and understanding the diffusion of plasticizers from polymers into the surrounding media.
