Highly efficient recovery of high-purity Cu, PVC, and phthal

Highly efficient recovery of high-purity Cu, PVC, and phthalate plasticizer from waste wire harnesses through PVC swelling and rod milling H. Kumar, S. Kumagai, T. Kameda, Y. Saito and T. Yoshioka, React. Reduction of the Additives Migration from Poly Vinyl PVC films. Migration tests were conducted using olive oil as fatty simulant and aqueous ethanol. The test conditions were 12 days at 40˚C (directive 82/711EEC). Twelve circular samples of plasticized PVC were immersed in 120 ml of food simulant. A circular

Comparative study on the migration of di-2-ethylhexyl

The PVC tubing plasticized with DEHP (di-2-ethylhexyl phthalate) was found to have the highest mass loss over time and showed a high plasticizer migration rate. In comparison, the migration of TOTM (tri-2-ethylhexyl trimellitate) and its primary degradation products was found to be distinctly lower (by a factor of approx. 350).

As expected, rigid PVC has the highest hVickers value. Migration of the plasticizer from the flexible sheets into rigid PVC lowers [h.sub.vickers] values by a whole order of magnitude.

In comparison, the migration of TOTM (tri-2-ethylhexyl trimellitate) and its primary degradation products was found to be distinctly lower (by a factor of approx. 350). Study of the Migration of Stabilizer and Plasticizer from Po High-purity deionized water (resistivity 18.2 MΩ cm −1) was prepared by using a water purification machine (Eped, Nanjing, China).

Nontoxic bio-plasticizers for PVC as replacements for

and high versatility [1–3]. However, pure PVC is a rigid polymer while many industries require PVC to have flexibility and processability [4]. In order to improve those two properties, PVC is often blended with plasticizers [5]. Unfortunately, often there is migration PVC plasticizers/additives migrating from the gaskets of 21/1/2006 · Foods with at least a few percent of free oil packed in glass jars with metal closures were analyzed for migration of additives, primarily plasticizers, from the gasket of the lid. One hundred and fifty-eight samples were collected in June 2005, i.e., some 10 months after the problem of excessive migration into oily food was communicated to the industry. In a first step, the composition of the

Phthalate Plasticizers Covalently Bound to PVC: Plasticizati

21/1/2010 · The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a good plasticization efficiency is achieved although flexibility is reduced compared with that of commercial PVC−phthalate systems. However, the migration is J. Braz. Chem.
