Machine translation, like DeepLorGoogle Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Consider adding a topic to this template: there are already 1,452 articles in the main category, and specifying|topic= will aid in categorization.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.

Eastman Tritan cannot be used for hot beverages (like hot water, coffee or tea) and is recommended only for usage temperatures below 60 °C, as it starts to deteriorate at temperatures above 80 °C.[4][5]
In April 2008, Nalgene announced it would phase out production of its outdoor line of polycarbonate containers containing the chemical bisphenol A.[6] Nalgene now uses Tritan as a replacement for polycarbonate, as it does not contain BPA.[7]
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.[8]
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]
Other manufacturers have developed similar products including the French ARC International's Kwarx since 2006,[9] the German Glaskoch [de] (Leonardo) Teqton since 2009[10] and the South-Korean SK Chemicals' Ecozen, a glycol-modified polyethylene terephthalate (PETG) since 2010/2011.[11] Other manufacturers propose polypropylene (PP)[12]ormethylstyrene (MS) as alternatives to Tritan.
