Tritan is 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).[1][2] Tritan is a copolymer made from three monomers: dimethyl terephthalate (DMT), cyclohexanedimethanol (CHDM), and 2,2,4,4-tetramethyl-1,3-cyclobutanediol (CBDO).[3] Tritan (PCTG) is made without using any BPA.
In April 2008, Nalgene announced it would phase out production of its outdoor line of polycarbonate containers containing the chemical bisphenol A.[4] Nalgene now uses Tritan as a replacement for polycarbonate, as it does not contain BPA.[5]
Health controversy
In 2011, a neurobiologist at the University of Texas, George Bittner, published an article claiming most polymers, including Tritan, contained other materials with estrogenic activity.[6]
Eastman Chemical Company sued, and after a jury ruled in Eastman's favor, the Court barred Bittner from making claims about Tritan's oestrogenic activity.[1]
Similar products
Other manufacturers have developed similar products including the French ARC International's Kwarx since 2006,[7] the German Glaskoch [de] (Leonardo) Teqton since 2009[8] and the South-Korean SK Chemicals' Ecozen, a glycol-modified polyethylene terephthalate (PETG) since 2010/2011.[9] Other manufacturers propose polypropylene (PP)[10] or methylstyrene (MS) as alternatives to Tritan.
Tritan[11] can also refer to a type of glass originally developed by the German Schott Zwiesel AG in 2002 together with University of Erlangen–Nuremberg.[12][13] Its name is derived from titanoxide (titanium oxide in English). In 2012, the Zwiesel Kristallglas AG introduced Tritan Protect.[13][14][15]
