Tritan copolyester

Tritan, a copolymer offered by the Eastman Chemical Company since 2007, is a transparent plastic intended to replace polycarbonate, because of health concerns about Bisphenol A (BPA).

[7] In 2011, a neurobiologist at the University of Texas at Austin, George Bittner, published an article claiming that most polymers, including Tritan, contained other materials with estrogenic activity.

[1] During the trial it emerged that Thomas Osimitz, an author of the journal article[9] that initially cleared Tritan of estrogenic activity, was paid $10,000 by the company for the paper and that this was not disclosed in the Conflict of Interests section.

"[10] Bittner maintains that his assays are more sensitive that the ones performed Osimitz et al.[1] Other manufacturers have developed similar products including the French Arc Holdings's Kwarx since 2006,[11] the German Glaskoch [de] (Leonardo) Teqton since 2009[12] and the South-Korean SK Chemicals' Ecozen, a glycol-modified polyethylene terephthalate (PETG) since 2010/2011.

Tritan[15] can also refer to a type of so called unbreakable glass originally developed by the German Zwiesel Kristallglas in 2002 together with University of Erlangen–Nuremberg.
